# This file is in the public domain, so clarified as of
# 2009-05-17 by Arthur David Olson.

# This file is by no means authoritative; if you think you know better,
# go ahead and edit the file (and please send any changes to
# tz@iana.org for general use in the future).  For more, please see
# the file CONTRIBUTING in the tz distribution.

# From Paul Eggert (2017-01-13):
#
# Unless otherwise specified, the source for data through 1990 is:
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
# San Diego: ACS Publications, Inc. (2003).
# Unfortunately this book contains many errors and cites no sources.
#
# Many years ago Gwillim Law wrote that a good source
# for time zone data was the International Air Transport
# Association's Standard Schedules Information Manual (IATA SSIM),
# published semiannually.  Law sent in several helpful summaries
# of the IATA's data after 1990.  Except where otherwise noted,
# IATA SSIM is the source for entries after 1990.
#
# Another source occasionally used is Edward W. Whitman, World Time Differences,
# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
# I found in the UCLA library.
#
# For data circa 1899, a common source is:
# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
# https://www.jstor.org/stable/1774359
#
# For Russian data circa 1919, a source is:
# Byalokoz EL. New Counting of Time in Russia since July 1, 1919.
# (See the 'europe' file for a fuller citation.)
#
# A reliable and entertaining source about time zones is
# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
#
# The following alphabetic abbreviations appear in these tables:
#	     std  dst
#	     LMT	Local Mean Time
#	2:00 EET  EEST	Eastern European Time
#	2:00 IST  IDT	Israel
#	5:30 IST	India
#	7:00 WIB	west Indonesia (Waktu Indonesia Barat)
#	8:00 WITA	central Indonesia (Waktu Indonesia Tengah)
#	8:00 CST	China
#	8:30 KST  KDT	Korea when at +0830
#	9:00 WIT	east Indonesia (Waktu Indonesia Timur)
#	9:00 JST  JDT	Japan
#	9:00 KST  KDT	Korea when at +09
#	9:30 ACST	Australian Central Standard Time
# Otherwise, these tables typically use numeric abbreviations like +03
# and +0330 for integer hour and minute UT offsets.  Although earlier
# editions invented alphabetic time zone abbreviations for every
# offset, this did not reflect common practice.
#
# See the 'europe' file for Russia and Turkey in Asia.

# From Guy Harris:
# Incorporates data for Singapore from Robert Elz' asia 1.1, as well as
# additional information from Tom Yap, Sun Microsystems Intercontinental
# Technical Support (including a page from the Official Airline Guide -
# Worldwide Edition).

# Armenia
# From Paul Eggert (2006-03-22):
# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)
# in spring 1991, then to 4:00 with no DST in fall 1995, then
# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even
# when they disagree with others.  Edgar Der-Danieliantz
# reported (1996-05-04) that Yerevan probably wouldn't use DST
# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
# but started switching at 3:00s in 1998.

# From Arthur David Olson (2011-06-15):
# While Russia abandoned DST in 2011, Armenia may choose to
# follow Russia's "old" rules.

# From Alexander Krivenyshev (2012-02-10):
# According to News Armenia, on Feb 9, 2012,
# http://newsarmenia.ru/society/20120209/42609695.html
#
# The Armenia National Assembly adopted final reading of Amendments to the
# Law "On procedure of calculation time on the territory of the Republic of
# Armenia" according to which Armenia [is] abolishing Daylight Saving Time.

# China

# From Guy Harris:
# People's Republic of China.  Yes, they really have only one time zone.

# From Bob Devine (1988-01-28):
# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
# China is across 4 physical time zones, before Feb 1, 1986 only the
# Peking (Beijing) time zone was recognized.  Since that date, China
# has two of 'em - Peking's and Ürümqi (named after the capital of
# the Xinjiang Uyghur Autonomous Region).  I don't know about DST for it.
#
# . . .I just deleted the DST table and this editor makes it too
# painful to suck in another copy.  So, here is what I have for
# DST start/end dates for Peking's time zone (info from AP):
#
#     1986 May 4 - Sept 14
#     1987 mid-April - ??

# From U. S. Naval Observatory (1989-01-19):
# CHINA               8 H  AHEAD OF UTC  ALL OF CHINA, INCL TAIWAN
# CHINA               9 H  AHEAD OF UTC  APR 17 - SEP 10

# Shanks & Pottenger have China switching to a single time zone in 1980, but

# therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege
# county is GMT+8 according to astro.com while Baiyu county is GMT+6
# (could be true), for the moment I am assuming that those two
# counties are mistakes in the astro.com data.

# From Paul Eggert (2017-01-05):
# Alois Treindl kindly sent me translations of the following two sources:
#
# (1)
# Guo Qingsheng (National Time-Service Center, CAS, Xi'an 710600, China)
# Beijing Time at the Beginning of the PRC
# China Historical Materials of Science and Technology
# (Zhongguo ke ji shi liao, 中国科技史料), Vol. 24, No. 1 (2003)
# It gives evidence that at the beginning of the PRC, Beijing time was
# officially apparent solar time!  However, Guo also says that the
# evidence is dubious, as the relevant institute of astronomy had not
# been taken over by the PRC yet.  It's plausible that apparent solar
# time was announced but never implemented, and that people continued
# to use UT+8.  As the Shanghai radio station (and I presume the
# observatory) was still under control of French missionaries, it
# could well have ignored any such mandate.
#
# (2)
# Guo Qing-sheng (Shaanxi Astronomical Observatory, CAS, Xi'an 710600, China)
# A Study on the Standard Time Changes for the Past 100 Years in China
# [undated and unknown publication location]
# It says several things:
#   * The Qing dynasty used local apparent solar time throughout China.
#   * The Republic of China instituted Beijing mean solar time effective
#     the official calendar book of 1914.
#   * The French Concession in Shanghai set up signal stations in
#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
#     Observatory and set to local mean time.
#   * "From the end of the 19th century" it changed to UT+8.
#   * Chinese Customs (by then reduced to a tool of foreign powers)
#     eventually standardized on this time for all ports, and it
#     became used by railways as well.
#   * In 1918 the Central Observatory proposed dividing China into
#     five time zones (see below for details).  This caught on
#     at first only in coastal areas observing UT+8.
#   * During WWII all of China was in theory was at UT+7.  In practice
#     this was ignored in the west, and I presume was ignored in
#     Japanese-occupied territory.
#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
#   * The five-zone plan was resurrected after WWII and officially put into
#     place (with some modifications) in March 1948.  It's not clear
#     how well it was observed in areas under Nationalist control.
#   * The People's Liberation Army used UT+8 during the civil war.
#
# An AP article "Shanghai Internat'l Area Little Changed" in the
# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is
# different - the occupied districts going by Tokyo time, an hour
# ahead of that prevailing in the rest of Shanghai."  Guess that the
# Xujiahui Observatory was under French control and stuck with UT +08.
#
# In earlier versions of this file, China had many separate Zone entries, but
# this was based on what were apparently incorrect data in Shanks & Pottenger.
# This has now been simplified to the two entries Asia/Shanghai and
# Asia/Urumqi, with the others being links for backward compatibility.
# Proposed in 1918 and theoretically in effect until 1949 (although in practice
# mainly observed in coastal areas), the five zones were:
#
# Changbai Time ("Long-white Time", Long-white = Heilongjiang area) UT +08:30
# Now part of Asia/Shanghai; its pre-1970 times are not recorded here.
# Heilongjiang (except Mohe county), Jilin
#
# Zhongyuan Time ("Central plain Time") UT +08
# Now part of Asia/Shanghai.
# most of China
# Milne gives 8:05:43.2 for Xujiahui Observatory time; round to nearest.
# Guo says Shanghai switched to UT +08 "from the end of the 19th century".
#
# Long-shu Time (probably as Long and Shu were two names of the area) UT +07
# Now part of Asia/Shanghai; its pre-1970 times are not recorded here.
# Guangxi, Guizhou, Hainan, Ningxia, Sichuan, Shaanxi, and Yunnan;
# most of Gansu; west Inner Mongolia; east Qinghai; and the Guangdong
# counties Deqing, Enping, Kaiping, Luoding, Taishan, Xinxing,
# Yangchun, Yangjiang, Yu'nan, and Yunfu.
#
# Xin-zang Time ("Xinjiang-Tibet Time") UT +06
# This region is now part of either Asia/Urumqi or Asia/Shanghai with
# current boundaries uncertain; times before 1970 for areas that
# disagree with Ürümqi or Shanghai are not recorded here.
# The Gansu counties Aksay, Anxi, Dunhuang, Subei; west Qinghai;
# the Guangdong counties  Xuwen, Haikang, Suixi, Lianjiang,
# Zhanjiang, Wuchuan, Huazhou, Gaozhou, Maoming, Dianbai, and Xinyi;
# east Tibet, including Lhasa, Chamdo, Shigaise, Jimsar, Shawan and Hutubi;
# east Xinjiang, including Ürümqi, Turpan, Karamay, Korla, Minfeng, Jinghe,
# Wusu, Qiemo, Xinyan, Wulanwusu, Jinghe, Yumin, Tacheng, Tuoli, Emin,
# Shihezi, Changji, Yanqi, Heshuo, Tuokexun, Tulufan, Shanshan, Hami,
# Fukang, Kuitun, Kumukuli, Miquan, Qitai, and Turfan.
#
# Kunlun Time UT +05:30
# This region is now in the same status as Xin-zang Time (see above).
# West Tibet, including Pulan, Aheqi, Shufu, Shule;
# West Xinjiang, including Aksu, Atushi, Yining, Hetian, Cele, Luopu, Nileke,
# Zhaosu, Tekesi, Gongliu, Chabuchaer, Huocheng, Bole, Pishan, Suiding,
# and Yarkand.

# From Luther Ma (2009-10-17):
# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
# but have no need of it. All planes, trains, and schools function on
# what is called "Beijing time." When Han make an appointment in Chinese
# they implicitly use Beijing time.
#
# On the other hand, ethnic Uyghurs, who make up about half the
# population of Xinjiang, typically use "Xinjiang time" which is two
# hours behind Beijing time, or UT +06. The government of the Xinjiang
# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
# local governments such as the Ürümqi city government use both times in
# publications, referring to what is popularly called Xinjiang time as
# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language
# they almost invariably use Xinjiang time.
#
# (Their ethnic Han compatriots would typically have no clue of its
# widespread use, however, because so extremely few of them are fluent in
# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
#
# (...As with the rest of China there was a brief interval ending in 1990
# or 1991 when summer time was in use.  The confusion was severe, with
# the province not having dual times but four times in use at the same
# time. Some areas remained on standard Xinjiang time or Beijing time and
# others moving their clocks ahead.)

# From Luther Ma (2009-11-19):
# With the risk of being redundant to previous answers these are the most common
# English "transliterations" (w/o using non-English symbols):
#
# 1. Wulumuqi...
# 2. Kashi...
# 3. Urumqi...
# 4. Kashgar...
# ...
# 5. It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the
# 1960's. I know of one Han, now over 50, who grew up in the surrounding
# countryside and used Xinjiang time as a child.
#
# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
# start date for Xinjiang time.
#
# Without having access to local historical records, nor the ability to legally
# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
# not be using Beijing time, but some local time.)

# From David Cochrane (2014-03-26):
# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986:
# https://content.time.com/time/magazine/article/0,9171,960684,00.html

# From Luther Ma (2014-04-22):
# I have interviewed numerous people of various nationalities and from
# different localities in Xinjiang and can confirm the information in Guo's
# report regarding Xinjiang, as well as the Time article reference by David
# Cochrane.  Whether officially recognized or not (and both are officially
# recognized), two separate times have been in use in Xinjiang since at least
# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time;
# and Beijing Time.  There is no confusion in Xinjiang as to which name refers
# to which time. Both are widely used in the province, although in some
# population groups might be use one to the exclusion of the other.  The only
# problem is that computers and smart phones list Ürümqi (or Kashgar) as
# having the same time as Beijing.

# From Paul Eggert (2014-06-30):
# In the early days of the PRC, Tibet was given its own time zone (UT +06)
# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun,
# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN
# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.
# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.
#
# Xinjiang Time is well-documented as being officially recognized.  E.g., see
# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22).
# Unfortunately, we have no good records of time in Xinjiang before 1986.
# During the 20th century parts of Xinjiang were ruled by the Qing dynasty,
# the Republic of China, various warlords, the First and Second East Turkestan
# Republics, the Soviet Union, the Kuomintang, and the People's Republic of
# China, and tracking down all these organizations' timekeeping rules would be
# quite a trick.  Approximate this lost history by a transition from LMT to
# UT +06 at the start of 1928, the year of accession of the warlord Jin Shuren,
# which happens to be the date given by Shanks & Pottenger (no doubt as a
# guess) as the transition from LMT.  Ignore the usage of +08 before
# 1986-02-01 under the theory that the transition date to +08 is unknown and
# that the sort of users who prefer Asia/Urumqi now typically ignored the
# +08 mandate back then.

# Taiwan

# From smallufo (2010-04-03):
# According to Taiwan's CWB [Central Weather Bureau],
# http://www.cwb.gov.tw/V6/astronomy/cdata/summert.htm
# Taipei has DST in 1979 between July 1st and Sep 30.

# From Yu-Cheng Chuang (2013-07-12):
# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
# Meiji Year 28 "The clause about standard time", mentioned that
# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
# (both in Okinawa) adopt the Western Standard Time which is based on
# 120E. The adoption began from Jan 1, 1896. The original text can be
# found on Wikisource:
# https://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
# ... This could be the first adoption of time zone in Taiwan, because
# during the Qing Dynasty, it seems that there was no time zone
# declared officially.
#
# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
# revision in the ordinance No. 167 of Meiji year 28 about standard
# time", in which abolished the adoption of Western Standard Time in
# western islands (listed above), which means the whole Japan
# territory, including later occupations, adopt Japan Central Time
# (UT+9). The adoption began on Oct 1, 1937. The original text can
# be found on Wikisource:
# https://ja.wikisource.org/wiki/明治二十八年勅令第百六十七號標準時ニ關スル件中改正ノ件
#
# That is, the time zone of Taipei switched to UT+9 on Oct 1, 1937.

# From Yu-Cheng Chuang (2014-07-02):
# I've found more evidence about when the time zone was switched from UT+9
# back to UT+8 after WW2.  I believe it was on Sep 21, 1945.  In a document
# during Japanese era [1] in which the officer told the staff to change time
# zone back to Western Standard Time (UT+8) on Sep 21.  And in another
# history page of National Cheng Kung University [2], on Sep 21 there is a
# note "from today, switch back to Western Standard Time".  From these two
# materials, I believe that the time zone change happened on Sep 21.  And
# today I have found another monthly journal called "The Astronomical Herald"
# from The Astronomical Society of Japan [3] in which it mentioned the fact
# that:
#
# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
# the time at 135E (GMT+9)
#
# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
# as well as Yaeyama and Miyako islands, adopted a new time zone called
# Western Standard Time, which is in GMT+8.
#
# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
# territories of Japan adopted the same time zone, which is Central Standard
# Time.

# Yu-Cheng Chuang (2014-07-03):
# I finally have found the real official gazette about changing back to
# Western Standard Time on Sep 21 in Taiwan.  It's Taiwan Governor-General
# Bulletin No. 386 in Showa 20 years (1945), published on Sep 19, 1945. [1] ...
# [It] abolishes Bulletin No. 207 in Showa 12 years (1937), which is a local
# bulletin in Taiwan for that Ordinance No. 529. It also mentioned that 1am on
# Sep 21, 1945 will be 12am on Sep 21.  I think this bulletin is much more
# official than the one I mentioned in my first mail, because it's from the
# top-level government in Taiwan. If you're going to quote any resource, this
# would be a good one.
# [1] Taiwan Governor-General Gazette, No. 1018, Sep 19, 1945:

# From Yu-Cheng Chuang (2014-07-02):
# In 1946, DST in Taiwan was from May 15 and ended on Sep 30. The info from
# Central Weather Bureau website was not correct.
#
# Original Bulletin:
# http://subtpg.tpg.gov.tw/og/image2.asp?f=03502F0AKM1AF
# http://subtpg.tpg.gov.tw/og/image2.asp?f=0350300AKM1B0 (cont.)
#
# In 1947, DST in Taiwan was expanded to Oct 31. There is a backup of that
# telegram announcement from Taiwan Province Government:
#
# http://subtpg.tpg.gov.tw/og/image2.asp?f=0360310AKZ431
#
# Here is a brief translation:
#
#   The Summer Time this year is adopted from midnight Apr 15 until Sep 20
#   midnight. To save (energy?) consumption, we're expanding Summer Time
#   adoption till Oct 31 midnight.
#
# The Central Weather Bureau website didn't mention that, however it can
# be found from historical government announcement database.

# From Paul Eggert (2014-07-03):
# As per Yu-Cheng Chuang, say that Taiwan was at UT +09 from 1937-10-01
# until 1945-09-21 at 01:00, overriding Shanks & Pottenger.
# Likewise, use Yu-Cheng Chuang's data for DST in Taiwan.

# Georgia
# From Paul Eggert (1994-11-19):
# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
# an hour recently, due to a law proposed by Zurab Murvanidze,
# an MP who went on a hunger strike for 11 days to force discussion about it!
# We have no details, but we'll guess they didn't move the clocks back in fall.
#
# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
# Instead of putting back clocks at the end of October, Georgia
# will stay on daylight savings time this winter to save energy,
# President Eduard Shevardnadze decreed Wednesday.
#
# From the BBC via Joseph S. Myers (2004-06-27):
#
# Georgia moved closer to Western Europe on Sunday...  The former Soviet
# republic has changed its time zone back to that of Moscow.  As a result it
# is now just four hours ahead of Greenwich Mean Time, rather than five hours
# ahead.  The switch was decreed by the pro-Western president of Georgia,
# Mikheil Saakashvili, who said the change was partly prompted by the process
# of integration into Europe.

# From Teimuraz Abashidze (2005-11-07):
# Government of Georgia ... decided to NOT CHANGE daylight savings time on
# [Oct.] 30, as it was done before during last more than 10 years.
# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
# about it.  As far as I can find, I was told, that there is no document,
# because we just DIDN'T ISSUE document about switching to winter time....
# I don't know what can be done, especially knowing that some years ago our
# DST rules where changed THREE TIMES during one month.

# Milne 1899 says Tbilisi (Tiflis) time was 2:59:05.7.
# Byalokoz 1919 says Georgia was 2:59:11.

# East Timor

# See Indonesia for the 1945 transition.

# From João Carrascalão, brother of the former governor of East Timor, in
# East Timor may be late for its millennium
# <https://etan.org/et99c/december/26-31/30ETMAY.htm> (1999-12-26/31):
# Portugal tried to change the time forward in 1974 because the sun
# rises too early but the suggestion raised a lot of problems with the
# Timorese and I still don't think it would work today because it
# conflicts with their way of life.

# From Paul Eggert (2000-12-04):
# We don't have any record of the above attempt.
# Most likely our records are incomplete, but we have no better data.

# From Manoel de Almeida e Silva, Deputy Spokesman for the UN Secretary-General
# http://www.hri.org/news/world/undh/2000/00-08-16.undh.html
# (2000-08-16):
# The Cabinet of the East Timor Transition Administration decided

# India

# From Ian P. Beacock, in "A brief history of (modern) time", The Atlantic
# https://www.theatlantic.com/technology/archive/2015/12/the-creation-of-modern-time/421419/
# (2015-12-22):
# In January 1906, several thousand cotton-mill workers rioted on the
# outskirts of Bombay....  They were protesting the proposed abolition of
# local time in favor of Indian Standard Time....  Journalists called this
# dispute the "Battle of the Clocks."  It lasted nearly half a century.

# From Paul Eggert (2017-04-20):
# Good luck trying to nail down old timekeeping records in India.
# "... in the nineteenth century ... Madras Observatory took its magnetic
# measurements on Göttingen time, its meteorological measurements on Madras
# (local) time, dropped its time ball on Greenwich (ocean navigator's) time,
# and distributed civil (local time)." -- Bartky IR. Selling the true time:
# 19th-century timekeeping in america. Stanford U Press (2000), 247 note 19.
# "A more potent cause of resistance to the general adoption of the present
# standard time lies in the fact that it is Madras time.  The citizen of
# Bombay, proud of being 'primus in Indis' and of Calcutta, equally proud of
# his city being the Capital of India, and - for a part of the year - the Seat
# of the Supreme Government, alike look down on Madras, and refuse to change
# the time they are using, for that of what they regard as a benighted
# Presidency; while Madras, having for long given the standard time to the
# rest of India, would resist the adoption of any other Indian standard in its
# place." -- Oldham RD. On Time in India: a suggestion for its improvement.
# Proceedings of the Asiatic Society of Bengal (April 1899), 49-55.
#
# "In 1870 ... Madras time - 'now used by the telegraph and regulated from the
# only government observatory' - was suggested as a standard railway time,
# first to be adopted on the Great Indian Peninsular Railway (GIPR)....
# Calcutta, Bombay, and Karachi, were to be allowed to continue with their
# local time for civil purposes." - Prasad R. Tracks of Change: Railways and
# Everyday Life in Colonial India. Cambridge University Press (2016), 145.
#
# Reed S, Low F. The Indian Year Book 1936-37. Bennett, Coleman, pp 27-8.
# https://archive.org/details/in.ernet.dli.2015.282212
# This lists +052110 as Madras local time used in railways, and says that on
# 1906-01-01 railways and telegraphs in India switched to +0530.  Some
# municipalities retained their former time, and the time in Calcutta
# continued to depend on whether you were at the railway station or at
# government offices.  Government time was at +055320 (according to Shanks) or
# at +0554 (according to the Indian Year Book).  Railway time is more
# appropriate for our purposes, as it was better documented, it is what we do
# elsewhere (e.g., Europe/London before 1880), and after 1906 it was
# consistent in the region now identified by Asia/Kolkata.  So, use railway
# time for 1870-1941.  Shanks is our only (and dubious) source for the
# 1941-1945 data.

#
# From Paul Eggert (2007-03-10):
# Here is another correction to Shanks & Pottenger.
# JohnTWB writes that Japanese forces did not surrender control in
# Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and
# other formal surrender ceremonies were September 9, 11, and 13, plus
# September 12 for the regional surrender to Mountbatten in Singapore.
# These would be the earliest possible times for a change.
# Régimes horaires pour le monde entier, by Henri Le Corre, (Éditions
# Traditionnelles, 1987, Paris) says that Java and Madura switched
# from UT +09 to +07:30 on 1945-09-23, and gives 1944-09-01 for Jayapura
# (Hollandia).  For now, assume all Indonesian locations other than Jayapura
# switched on 1945-09-23.
#
# From Paul Eggert (2013-08-11):

# Iran

# From Roozbeh Pournader (2003-03-15):
# This is an English translation of what I just found (originally in Persian).
# The Gregorian dates in brackets are mine:
#
#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
#	No. 16760/T233 H				1370/6/10 [1991-09-01]
#
#	The Rule About Change of the Official Time of the Country
#
#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
#	of the Country's Organization for Official and Employment Affairs,
#	and referring to the law for equating the working hours of workers
#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
#	for synchronizing the official times of the country, agreed that:
#
#	The official time of the country will should move forward one hour
#	at the 24[:00] hours of the first day of Farvardin and should return
#	to its previous state at the 24[:00] hours of the 30th day of
#	Shahrivar.
#
#	First Deputy to the President - Hassan Habibi
#
# From personal experience, that agrees with what has been followed
# for at least the last 5 years.  Before that, for a few years, the
# date used was the first Thursday night of Farvardin and the last
# Thursday night of Shahrivar, but I can't give exact dates....
#
# From Roozbeh Pournader (2005-04-05):
# The text of the Iranian law, in effect since 1925, clearly mentions
# that the true solar year is the measure, and there is no arithmetic
# leap year calculation involved.  There has never been any serious
# plan to change that law....
#
# From Paul Eggert (2006-03-22):
# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
# stopping after 2037 when 32-bit time_t's overflow.
# That cal-persia used Birashk's approximation, which disagrees with the solar
# calendar predictions for the year 2025, so I corrected those dates by hand.
#
# From Oscar van Vlijmen (2005-03-30), writing about future
# discrepancies between cal-persia and the Iranian calendar:
# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
# the vernal equinox and that gets so close to 12:00 some local
# Iranian time that the definition of the correct location needs to be
# known exactly, amongst other factors.  2157 is even closer:
# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give

# Iraq
#
# From Jonathan Lennox (2000-06-12):
# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
# the U.S. edition) on the Iraqi Kurds contains a paragraph:
# "The three northern provinces ... switched their clocks this spring and
# are an hour ahead of Baghdad."
#
# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
# In the past, some Kurdish nationalists, as a protest to the Iraqi
# Government, did not adhere to daylight saving time.  They referred
# to daylight saving as Saddam time.  But, as of today, the time zone
# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
#
# So we'll ignore the Economist's claim.

# From Steffen Thorsen (2008-03-10):
# The cabinet in Iraq abolished DST last week, according to the following
# news sources (in Arabic):
# http://www.aljeeran.net/wesima_articles/news-20080305-98602.html

# Israel

# From Ephraim Silverberg (2001-01-11):
#
# I coined "IST/IDT" circa 1988.  Until then there were three
# different abbreviations in use:
#
# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
# EEST Eastern Europe Standard Time [used by almost everyone else]
#
# Since timezones should be called by country and not capital cities,
# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
# EEST was equally unacceptable.  Since "zonal" was not compatible with
# any other timezone abbreviation, I felt that 'IST' was the way to go
# and, indeed, it has received almost universal acceptance in timezone
# settings in Israeli computers.
#
# In any case, I am happy to share timezone abbreviations with India,
# high on my favorite-country list (and not only because my wife's
# family is from India).

# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
# and 2005-02-17):

# According to the Office of the Secretary General of the Ministry of
# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
# One thing is entrenched in law, however: that there must be at least 150
# days of daylight savings time annually.  From 1993-1998, the change to
# daylight savings time was on a Friday morning from midnight IST to
# 1 a.m IDT; up until 1998, the change back to standard time was on a
# Saturday night from midnight daylight savings time to 11 p.m. standard
# time.  1996 is an exception to this rule where the change back to standard
# time took place on Sunday night instead of Saturday night to avoid
# conflicts with the Jewish New Year.  In 1999, the change to
# daylight savings time was still on a Friday morning but from
# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
# 1999 only.  In the year 2000, the change to daylight savings time was
# similar to 1999, but although the change back will be on a Friday, it
# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
# changes to/from will take place at 1 a.m. old time, but now there is no
# rule as to what day of the week it will take place in as the start date
# (except in 2003) is the night after the Passover Seder (i.e. the eve
# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

# '9:00' and 'JST' is from Guy Harris.

# From Paul Eggert (1995-03-06):
# Today's _Asahi Evening News_ (page 4) reports that Japan had

# http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm
# Occupation authorities imposed daylight-saving time on Japan on
# [1948-05-01]....  But lack of prior debate and the execution of
# daylight-saving time just three days after the bill was passed generated
# deep hatred of the concept....  The Diet unceremoniously passed a bill to
# dump the unpopular system in October 1951, less than a month after the San
# Francisco Peace Treaty was signed.  (A government poll in 1951 showed 53%
# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
# wanted to keep it.)

# The ordinance No. 51 (1886) established "standard time" in Japan,
# which stands for the time on 135° E.
# In the ordinance No. 167 (1895), "standard time" was renamed to "central
# standard time".  And the same ordinance also established "western standard
# time", which stands for the time on 120° E....  But "western standard
# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.
# 167, there is no mention regarding for what place western standard time is
# standard....
#
# I wrote "ordinance" above, but I don't know how to translate.

# Winter time starts today Thursday, 30 September. Clocks will be turned back

# Kazakhstan

# From Kazakhstan Embassy's News Bulletin No. 11
# <http://www.kazsociety.org.uk/news/2005/03/30.htm> (2005-03-21):
# The Government of Kazakhstan passed a resolution March 15 abolishing
# daylight saving time citing lack of economic benefits and health
# complications coupled with a decrease in productivity.
#
# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
# ... what happened was that the former Kazakhstan Eastern time zone
# was "blended" with the Central zone.  Therefore, Kazakhstan now has
# two time zones, and difference between them is one hour.  The zone
# closer to UTC is the former Western zone (probably still called the
# same), encompassing four provinces in the west: Aqtöbe, Atyraū,
# Mangghystaū, and West Kazakhstan.  The other zone encompasses
# everything else....  I guess that would make Kazakhstan time zones
# de jure UTC+5 and UTC+6 respectively.

# From Stepan Golosunov (2016-03-27):
# Review of the linked documents from http://adilet.zan.kz/
# produced the following data for post-1991 Kazakhstan:
#
# 0. Act of the Cabinet of Ministers of the USSR
# from 1991-02-04 No. 20
# http://pravo.gov.ru/proxy/ips/?docbody=&nd=102010545
# removed the extra hour ("decree time") on the territory of the USSR
# starting with the last Sunday of March 1991.
# It also allowed (but not mandated) Kazakh SSR, Kirghiz SSR, Tajik SSR,
# Turkmen SSR and Uzbek SSR to not have "summer" time.
#
# The 1992-01-13 act also refers to the act of the Cabinet of Ministers
# of the Kazakh SSR from 1991-03-20 No. 170 "About the act of the Cabinet
# of Ministers of the USSR from 1991-02-04 No. 20" but I didn't found its
# text.
#
# According to Izvestia newspaper No. 68 (23334) from 1991-03-20
# (page 6; available at http://libinfo.org/newsr/newsr2574.djvu via
# http://libinfo.org/index.php?id=58564) on 1991-03-31 at 2:00 during
# transition to "summer" time:
# Republic of Georgia, Latvian SSR, Lithuanian SSR, SSR Moldova,
# Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug
# were to move clocks 1 hour forward.
# Kazakh SSR (excluding Uralsk oblast); Republic of Kyrgyzstan, Tajik
# SSR; Andijan, Jizzakh, Namangan, Sirdarya, Tashkent, Fergana oblasts
# of the Uzbek SSR were to move clocks 1 hour backwards.
# Other territories were to not move clocks.
# When the "summer" time would end on 1991-09-29, clocks were to be
# moved 1 hour backwards on the territory of the USSR excluding
# Kazakhstan, Kirghizia, Uzbekistan, Turkmenia, Tajikistan.
#
# Apparently there were last minute changes. Apparently Kazakh act No. 170
# was one of such changes.
#
# https://ru.wikipedia.org/wiki/Декретное время
# claims that Sovetskaya Rossiya newspaper on 1991-03-29 published that
# Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast)
# were to not move clocks and Uralsk oblast was to move clocks
# forward; on 1991-09-29 Kazakhstan was to move clocks backwards.
# (Probably there were changes even after that publication. There is an
# article claiming that Kaliningrad oblast decided on 1991-03-29 to not
# move clocks.)
#
# This implies that on 1991-03-31 Asia/Oral remained on +04/+05 while
# the rest of Kazakhstan switched from +06/+07 to +05/06 or from +05/06
# to +04/+05. It's unclear how Qyzylorda oblast moved into the fifth
# time belt. (By switching from +04/+05 to +05/+06 on 1991-09-29?) ...
#
# 1. Act of the Cabinet of Ministers of the Republic of Kazakhstan
# from 1992-01-13 No. 28
# http://adilet.zan.kz/rus/docs/P920000028_
# (text includes modification from the 1996 act)
# introduced new rules for calculation of time, mirroring Russian
# 1992-01-08 act.  It specified that time would be calculated
# according to time belts plus extra hour ("decree time"), moved clocks
# on the whole territory of Kazakhstan 1 hour forward on 1992-01-19 at
# 2:00, specified DST rules.  It acknowledged that Kazakhstan was
# located in the fourth and the fifth time belts and specified the
# border between them to be located east of Qostanay and Aktyubinsk
# oblasts (notably including Turgai and Qyzylorda oblasts into the fifth
# time belt).
#
# This means switch on 1992-01-19 at 2:00 from +04/+05 to +05/+06 for
# Asia/Aqtau, Asia/Aqtobe, Asia/Oral, Atyraū and Qostanay oblasts; from
# +05/+06 to +06/+07 for Asia/Almaty and Asia/Qyzylorda (and Arkalyk)....
#
# 2. Act of the Cabinet of Ministers of the Republic of Kazakhstan
# from 1992-03-27 No. 284
# http://adilet.zan.kz/rus/docs/P920000284_
# cancels extra hour ("decree time") for Uralsk and Qyzylorda oblasts
# since the last Sunday of March 1992, while keeping them in the fourth
# and the fifth time belts respectively.
#
# 3. Order of the Prime Minister of the Republic of Kazakhstan
# from 1994-09-23 No. 384
# http://adilet.zan.kz/rus/docs/R940000384_
# cancels the extra hour ("decree time") on the territory of Mangghystaū
# oblast since the last Sunday of September 1994 (saying that time on
# the territory would correspond to the third time belt as a
# result)....
#
# 4. Act of the Government of the Republic of Kazakhstan
# from 1996-05-08 No. 575
# http://adilet.zan.kz/rus/docs/P960000575_
# amends the 1992-01-13 act to end summer time in October instead
# of September, mirroring identical Russian change from 1996-04-23 act.
#
# 5. Act of the Government of the Republic of Kazakhstan
# from 1999-03-26 No. 305
# http://adilet.zan.kz/rus/docs/P990000305_
# cancels the extra hour ("decree time") for Atyraū oblast since the
# last Sunday of March 1999 while retaining the oblast in the fourth
# time belt.
#
# This means change from +05/+06 to +04/+05....
#
# 6. Act of the Government of the Republic of Kazakhstan
# from 2000-11-23 No. 1749
# http://adilet.zan.kz/rus/archive/docs/P000001749_/23.11.2000
# replaces the previous five documents.
#
# The only changes I noticed are in definition of the border between the
# fourth and the fifth time belts.  They account for changes in spelling
# and administrative division (splitting of Turgai oblast in 1997
# probably changed time in territories incorporated into Qostanay oblast
# (including Arkalyk) from +06/+07 to +05/+06) and move Qyzylorda oblast
# from being in the fifth time belt and not using decree time into the
# fourth time belt (no change in practice).
#
# 7. Act of the Government of the Republic of Kazakhstan
# from 2003-12-29 No. 1342
# http://adilet.zan.kz/rus/docs/P030001342_
# modified the 2000-11-23 act.  No relevant changes, apparently.
#
# 8. Act of the Government of the Republic of Kazakhstan
# from 2004-07-20 No. 775
# http://adilet.zan.kz/rus/archive/docs/P040000775_/20.07.2004
# modified the 2000-11-23 act to move Qostanay and Qyzylorda oblasts into
# the fifth time belt and add Aktobe oblast to the list of regions not
# using extra hour ("decree time"), leaving Kazakhstan with only 2 time
# zones (+04/+05 and +06/+07).  The changes were to be implemented
# during DST transitions in 2004 and 2005 but the acts got radically
# amended before implementation happened.
#
# 9. Act of the Government of the Republic of Kazakhstan
# from 2004-09-15 No. 1059
# http://adilet.zan.kz/rus/docs/P040001059_
# modified the 2000-11-23 act to remove exceptions from the "decree time"
# (leaving Kazakhstan in +05/+06 and +06/+07 zones), amended the
# 2004-07-20 act to implement changes for Atyraū, West Kazakhstan,
# Qostanay, Qyzylorda and Mangghystaū oblasts by not moving clocks
# during the 2004 transition to "winter" time.
#
# This means transition from +04/+05 to +05/+06 for Atyraū oblast (no
# zone currently), Asia/Oral, Asia/Aqtau and transition from +05/+06 to
# +06/+07 for Qostanay oblast (Qostanay and Arkalyk, no zones currently)
# and Asia/Qyzylorda on 2004-10-31 at 3:00....
#
# 10. Act of the Government of the Republic of Kazakhstan
# from 2005-03-15 No. 231
# http://adilet.zan.kz/rus/docs/P050000231_
# removes DST provisions from the 2000-11-23 act, removes most of the
# (already implemented) provisions from the 2004-07-20 and 2004-09-15
# acts, comes into effect 10 days after official publication.
# The only practical effect seems to be the abolition of the summer
# time.
#
# Unamended version of the act of the Government of the Russian Federation
# No. 23 from 1992-01-08 [See 'europe' file for details].
# Kazakh 1992-01-13 act appears to provide the same rules and 1992-03-27
# act was to be enacted on the last Sunday of March 1992.

# From Stepan Golosunov (2016-11-08):
# Turgai reorganization should affect only southern part of Qostanay
# oblast.  Which should probably be separated into Asia/Arkalyk zone.
# (There were also 1970, 1988 and 1990 Turgai oblast reorganizations
# according to wikipedia.)
#
# [For Qostanay] http://www.ng.kz/gazeta/195/hranit/
# suggests that clocks were to be moved 40 minutes backwards on
# 1920-01-01 to the fourth time belt.  But I do not understand
# how that could happen....
#
# [For Atyrau and Oral] 1919 decree
# (http://www.worldtimezone.com/dst_news/dst_news_russia-1919-02-08.html
# and in Byalokoz) lists Ural river (plus 10 versts on its left bank) in
# the third time belt (before 1930 this means +03).

# The Korean Wikipedia entry gives the following sources for UT offsets:
#
# 1908: Official Journal Article No. 3994 (decree No. 5)
# 1912: Governor-General of Korea Official Gazette Issue No. 367
#       (Announcement No. 338)
# 1954: Presidential Decree No. 876 (1954-03-17)
# 1961: Law No. 676 (1961-08-07)
#
# (Another source "1987: Law No. 3919 (1986-12-31)" was in the 2014-10-30
# edition of the Korean Wikipedia entry.)
#
# I guessed that time zone abbreviations through 1945 followed the same
# rules as discussed under Taiwan, with nominal switches from JST to KST
# when the respective cities were taken over by the Allies after WWII.
#
# For Pyongyang, guess no changes from World War II until 2015, as we

# From Steffen Thorsen (2015-08-07):
# According to many news sources, North Korea is going to change to
# the 8:30 time zone on August 15, one example:

# http://news.yahoo.com/north-korea-celebrates-time-zone-pyongyang-time-164038128.html
# There is no common English-language abbreviation for this time zone.
# Use KST, as that's what we already use for 1954-1961 in ROK.

# From Kang Seonghoon (2018-04-29):

# Mongolia

# Shanks & Pottenger say that Mongolia has three time zones, but
# The USNO (1995-12-21) and the CIA map Standard Time Zones of the World
# (2005-03) both say that it has just one.

# From Oscar van Vlijmen (1999-12-11):
# General Information Mongolia
# <http://www.mongoliatourism.gov.mn/general.htm> (1999-09)
# "Time: Mongolia has two time zones. Three westernmost provinces of
# Bayan-Ölgii, Uvs, and Hovd are one hour earlier than the capital city, and
# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus
# eight hours."

# From Rives McDow (1999-12-13):
# Mongolia discontinued the use of daylight savings time in 1999; 1998
# being the last year it was implemented.  The dates of implementation I am
# unsure of, but most probably it was similar to Russia, except for the time
# of implementation may have been different....
# Some maps in the past have indicated that there was an additional time
# zone in the eastern part of Mongolia, including the provinces of Dornod,
# Sükhbaatar, and possibly Khentii.

# From Paul Eggert (1999-12-15):
# Naming and spelling is tricky in Mongolia.
# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
# and sometimes Jirgalanta (with variant spellings), but the name Hovd
# is good enough for our purposes.

# From Rives McDow (2001-05-13):
# In addition to Mongolia starting daylight savings as reported earlier
# (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28),
# there are three time zones.
#
# Provinces [at 7:00]: Bayan-Ölgii, Uvs, Khovd, Zavkhan, Govi-Altai
# Provinces [at 8:00]: Khövsgöl, Bulgan, Arkhangai, Khentii, Töv,
#	Bayankhongor, Övörkhangai, Dundgovi, Dornogovi, Ömnögovi
# Provinces [at 9:00]: Dornod, Sükhbaatar
#
# [The province of Selenge is omitted from the above lists.]

# From Ganbold Ts., Ulaanbaatar (2004-04-17):
# Daylight saving occurs at 02:00 local time last Saturday of March.
# It will change back to normal at 02:00 local time last Saturday of
# September.... As I remember this rule was changed in 2001.
#
# From Paul Eggert (2004-04-17):
# For now, assume Rives McDow's informant got confused about Friday vs
# Saturday, and that his 2001 dates should have 1 added to them.

# From Paul Eggert (2005-07-26):
# We have wildly conflicting information about Mongolia's time zones.
# Bill Bonnet (2005-05-19) reports that the US Embassy in Ulaanbaatar says
# there is only one time zone and that DST is observed, citing Microsoft
# Windows XP as the source.  Risto Nykänen (2005-05-16) reports that
# travelmongolia.org says there are two time zones (UT +07, +08) with no DST.
# Oscar van Vlijmen (2005-05-20) reports that the Mongolian Embassy in
# Washington, DC says there are two time zones, with DST observed.
# He also found
# http://ubpost.mongolnews.mn/index.php?subaction=showcomments&id=1111634894&archive=&start_from=&ucat=1&
# which also says that there is DST, and which has a comment by "Toddius"
# (2005-03-31 06:05 +0700) saying "Mongolia actually has 3.5 time zones.
# The West (OLGII) is +7 GMT, most of the country is ULAT is +8 GMT
# and some Eastern provinces are +9 GMT but Sükhbaatar Aimag is SUHK +8.5 GMT.
# The SUKH timezone is new this year, it is one of the few things the
# parliament passed during the tumultuous winter session."
# For now, let's ignore this information, until we have more confirmation.

# From Ganbold Ts. (2007-02-26):
# Parliament of Mongolia has just changed the daylight-saving rule in February.
# They decided not to adopt daylight-saving time....
# http://www.mongolnews.mn/index.php?module=unuudur&sec=view&id=15742

# From Deborah Goldsmith (2008-03-30):
# We received a bug report claiming that the tz database UTC offset for
# Asia/Choibalsan (GMT+09:00) is incorrect, and that it should be GMT
# +08:00 instead. Different sources appear to disagree with the tz
# database on this, e.g.:
#
# https://www.timeanddate.com/worldclock/city.html?n=1026
# http://www.worldtimeserver.com/current_time_in_MN.aspx
#
# both say GMT+08:00.

# From Steffen Thorsen (2008-03-31):
# eznis airways, which operates several domestic flights, has a flight
# schedule here:
# http://www.eznis.com/Container.jsp?id=112
# (click the English flag for English)
#
# There it appears that flights between Choibalsan and Ulaanbaatar arrive
# about 1:35 - 1:50 hours later in local clock time, no matter the
# direction, while Ulaanbaatar-Khovd takes 2 hours in the Eastern
# direction and 3:35 back, which indicates that Ulaanbaatar and Khovd are
# in different time zones (like we know about), while Choibalsan and
# Ulaanbaatar are in the same time zone (correction needed).

# From Arthur David Olson (2008-05-19):
# Assume that Choibalsan is indeed offset by 8:00.
# XXX--in the absence of better information, assume that transition
# was at the start of 2008-03-31 (the day of Steffen Thorsen's report);
# this is almost surely wrong.

# From Ganbold Tsagaankhuu (2015-03-10):
# It seems like yesterday Mongolian Government meeting has concluded to use
# daylight saving time in Mongolia....  Starting at 2:00AM of last Saturday of
# March 2015, daylight saving time starts.  And 00:00AM of last Saturday of
# September daylight saving time ends.  Source:

# Pakistan

# From Rives McDow (2002-03-13):
# I have been advised that Pakistan has decided to adopt dst on a
# TRIAL basis for one year, starting 00:01 local time on April 7, 2002
# and ending at 00:01 local time October 6, 2002.  This is what I was
# told, but I believe that the actual time of change may be 00:00; the
# 00:01 was to make it clear which day it was on.

# From Paul Eggert (2002-03-15):
# Jesper Nørgaard found this URL:
# http://www.pak.gov.pk/public/news/app/app06_dec.htm
# (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
# advance the clocks by one hour on the night between the first
# Saturday and Sunday of April and revert to the original position on
# 15th October each year".  This agrees with McDow's 04-07 at 00:00,
# but disagrees about the October transition, and makes it sound like
# it's not on a trial basis.  Also, the "between the first Saturday
# and Sunday of April" phrase, if taken literally, means that the
# transition takes place at 00:00 on the first Sunday on or after 04-02.

# From Paul Eggert (2003-02-09):
# DAWN <http://www.dawn.com/2002/10/06/top13.htm> reported on 2002-10-05

# Palestine

# From Amos Shapir (1998-02-15):
#
# From 1917 until 1948-05-15, all of Palestine, including the parts now
# known as the Gaza Strip and the West Bank, was under British rule.
# Therefore the rules given for Israel for that period, apply there too...
#
# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
# (except a short occupation by Israel from 1956-11 till 1957-03, but no
# time zone was affected then).  It was never formally annexed to Egypt,
# though.
#
# The rest of Palestine was under Jordanian rule at that time, formally
# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
# the country's previous name of "the Hashemite Kingdom of the
# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
# East Jerusalem.
#
# Both areas were occupied by Israel in June 1967, but not annexed (except
# for East Jerusalem).  They were on Israel time since then; there might
# have been a Military Governor's order about time zones, but I'm not aware
# of any (such orders may have been issued semi-annually whenever summer
# time was in effect, but maybe the legal aspect of time was just neglected).
#
# The Palestinian Authority was established in 1993, and got hold of most
# towns in the West Bank and Gaza by 1995.  I know that in order to
# demonstrate...independence, they have been switching to
# summer time and back on a different schedule than Israel's, but I don't
# know when this was started, or what algorithm is used (most likely the
# Jordanian one).
#
# To summarize, the table should probably look something like that:
#
# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
# ------------+-----------+-----------+-----------+-----------
# Israel      | Zion      | Zion      | Zion      | Zion
# West bank   | Zion      | Jordan    | Zion      | Jordan
# Gaza        | Zion      | Egypt     | Zion      | Jordan
#
# I guess more info may be available from the PA's web page (if/when they
# have one).

# From Paul Eggert (2006-03-22):
# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
# with Shapir and assume that it observed DST from 1940 through 1947,
# and that it used Jordanian rules starting in 1996.
# We don't yet need a separate entry for the West Bank, since
# the only differences between it and Gaza that we know about
# occurred before our cutoff date of 1970.
# However, as we get more information, we may need to add entries
# for parts of the West Bank as they transitioned from Israel's rules
# to Palestine's rules.

# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
# forwarded by Ephraim Silverberg:
#
# Despite the fact that Israel changed over to daylight savings time
# last week, the PLO Authority (PA) has decided not to turn its clocks
# one-hour forward at this time.  As a sign of independence from Israeli rule,
# the PA has decided to implement DST in April.

# From Paul Eggert (1999-09-20):
# Daoud Kuttab writes in Holiday havoc
# http://www.jpost.com/com/Archive/22.Apr.1999/Opinion/Article-2.html
# (Jerusalem Post, 1999-04-22) that
# the Palestinian National Authority changed to DST on 1999-04-15.
# I vaguely recall that they switch back in October (sorry, forgot the source).
# For now, let's assume that the spring switch was at 24:00,
# and that they switch at 0:00 on the 3rd Fridays of April and October.

# From Paul Eggert (2005-11-22):
# Starting 2004 transitions are from Steffen Thorsen's web site timeanddate.com.

# From Steffen Thorsen (2005-11-23):
# A user from Gaza reported that Gaza made the change early because of
# the Ramadan.  Next year Ramadan will be even earlier, so I think
# there is a good chance next year's end date will be around two weeks
# earlier - the same goes for Jordan.

# From Steffen Thorsen (2006-08-17):
# I was informed by a user in Bethlehem that in Bethlehem it started the
# same day as Israel, and after checking with other users in the area, I
# was informed that they started DST one day after Israel.  I was not
# able to find any authoritative sources at the time, nor details if
# Gaza changed as well, but presumed Gaza to follow the same rules as
# the West Bank.

# From Steffen Thorsen (2006-09-26):
# according to the Palestine News Network (2006-09-19):
# http://english.pnn.ps/index.php?option=com_content&task=view&id=596&Itemid=5
# > The Council of Ministers announced that this year its winter schedule
# > will begin early, as of midnight Thursday.  It is also time to turn
# > back the clocks for winter.  Friday will begin an hour late this week.
# I guess it is likely that next year's date will be moved as well,
# because of the Ramadan.

# From Jesper Nørgaard Welen (2007-09-18):
# According to Steffen Thorsen's web site the Gaza Strip and the rest of the
# Palestinian territories left DST early on 13.th. of September at 2:00.

# From Paul Eggert (2007-09-20):
# My understanding is that Gaza and the West Bank disagree even over when
# the weekend is (Thursday+Friday versus Friday+Saturday), so I'd be a bit
# surprised if they agreed about DST.  But for now, assume they agree.
# For lack of better information, predict that future changes will be
# the 2nd Thursday of September at 02:00.

# From Alexander Krivenyshev (2008-08-28):
# Here is an article, that Mideast running on different clocks at Ramadan.
#
# Gaza Strip (as Egypt) ended DST at midnight Thursday (Aug 28, 2008), while
# the West Bank will end Daylight Saving Time at midnight Sunday (Aug 31, 2008).

# Philippines
# On 1844-08-16, Narciso Clavería, governor-general of the
# Philippines, issued a proclamation announcing that 1844-12-30 was to
# be immediately followed by 1845-01-01; see R.H. van Gent's
# History of the International Date Line
# https://www.staff.science.uu.nl/~gent0113/idl/idl_philippines.htm

# March-June, but this is not definite.  It also says DST was last proclaimed

# Saudi Arabia
#
# From Paul Eggert (2014-07-15):
# Time in Saudi Arabia and other countries in the Arabian peninsula was not
# standardized until relatively recently; we don't know when, and possibly it
# has never been made official.  Richard P Hunt, in "Islam city yielding to
# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
# observed standard time, and that people in Jeddah mostly observed quasi-solar
# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
# o'clock for "Arab" time).
#
# The TZ database cannot represent quasi-solar time; airline time is the best
# we can do.  The 1946 foreign air news digest of the U.S. Civil Aeronautics
# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
# Jidda, on March 14, 1947".  Shanks & Pottenger guessed 1950; go with the
# earlier date.
#
# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two
# time zones; the other zone, at UT +04, was in the far eastern part of
# the country.  Ignore this, as it's before our 1970 cutoff.

# Sri Lanka

# From Paul Eggert (2013-02-21):
# Milne says "Madras mean time use from May 1, 1898.  Prior to this Colombo
# mean time, 5h. 4m. 21.9s. F., was used."  But 5:04:21.9 differs considerably
# from Colombo's meridian 5:19:24, so for now ignore Milne and stick with
# Shanks and Pottenger.

# From Paul Eggert (1996-09-03):
# "Sri Lanka advances clock by an hour to avoid blackout"
# (<http://www.virtual-pc.com/lankaweb/news/items/240596-2.html>, 1996-05-24,
# no longer available as of 1999-08-17)
# reported "the country's standard time will be put forward by one hour at
# midnight Friday (1830 GMT) 'in the light of the present power crisis'."
#
# From Dharmasiri Senanayake, Sri Lanka Media Minister (1996-10-24), as quoted
# by Shamindra in Daily News - Hot News Section
# <news:54rka5$m5h@mtinsc01-mgt.ops.worldnet.att.net> (1996-10-26):
# With effect from 12.30 a.m. on 26th October 1996
# Sri Lanka will be six (06) hours ahead of GMT.

# From Jesper Nørgaard Welen (2006-04-14), quoting Sri Lanka News Online
# <http://news.sinhalaya.com/wmview.php?ArtID=11002> (2006-04-13):
# 0030 hrs on April 15, 2006 (midnight of April 14, 2006 +30 minutes)
# at present, become 2400 hours of April 14, 2006 (midnight of April 14, 2006).

# From Peter Apps and Ranga Sirila of Reuters (2006-04-12) in:

# [The Tamil Tigers] never accepted the original 1996 time change and simply
# kept their clocks set five and a half hours ahead of Greenwich Mean
# Time (GMT), in line with neighbor India.
# From Paul Eggert (2006-04-18):
# People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
# as that zone has agreed with the Tamil areas since our cutoff date of 1970.

# From Sadika Sumanapala (2016-10-19):
# According to http://www.sltime.org (maintained by Measurement Units,
# Standards & Services Department, Sri Lanka) abbreviation for Sri Lanka
# standard time is SLST.
#
# From Paul Eggert (2016-10-18):
# "SLST" seems to be reasonably recent and rarely-used outside time
# zone nerd sources.  I searched Google News and found three uses of
# it in the International Business Times of India in February and
# March of this year when discussing cricket match times, but nothing
# since then (though there has been a lot of cricket) and nothing in
# other English-language news sources.  Our old abbreviation "LKT" is
# even worse.  For now, let's use a numeric abbreviation; we can
# switch to "SLST" if it catches on.

# ...which reads (in part) "The Cabinet approved the suggestion of the

# 4th, advancing clocks one hour ahead on midnight of Thursday April 3rd."
# Since Syria is two hours east of UTC, the 2200 and 2100 transition times

# From Arthur David Olson (2008-03-18):
# My best guess at a Syrian rule is "the Friday nearest April 1";

# compilers can't handle  or having multiple Rules (a la Israel).
# For now, use "Apr Fri>=1", and go with IATA on a uniform Sep 30 end.

# From Steffen Thorsen (2008-10-07):

# The article is in Arabic, and seems to tell that they will go back to

# and Pottenger for LMT before 1906.

# From Arthur David Olson (2008-03-18):
# The English-language name of Vietnam's most populous city is "Ho Chi Minh
# City"; use Ho_Chi_Minh below to avoid a name of more than 14 characters.

# From Paul Eggert (2014-10-21) after a heads-up from Trần Ngọc Quân:
# Trần Tiến Bình's authoritative book "Lịch Việt Nam: thế kỷ XX-XXI (1901-2100)"
# (Nhà xuất bản Văn Hoá - Thông Tin, Hanoi, 2005), pp 49-50,
# is quoted verbatim in:
# http://www.thoigian.com.vn/?mPage=P80D01
# is translated by Brian Inglis in:
# https://mm.icann.org/pipermail/tz/2014-October/021654.html
# and is the basis for the information below.
#
# The 1906 transition was effective July 1 and standardized Indochina to
# Phù Liễn Observatory, legally 104° 17' 17" east of Paris.
# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
# the Paris Meridian (2° 20' 14.03" E); the former yields 07:06:30.1333...
# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
# which is used below even though the modern-day Phù Liễn Observatory
# is closer to 07:06:31.  Abbreviate Phù Liễn Mean Time as PLMT.
#
# The following transitions occurred in Indochina in general (before 1954)
# and in South Vietnam in particular (after 1954):
# To 07:00 on 1911-05-01.
# To 08:00 on 1942-12-31 at 23:00.
# To 09:00 in 1945-03-14 at 23:00.
# To 07:00 on 1945-09-02 in Vietnam.
