# tzdb data for ships at sea and other miscellany # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. # These entries are mostly present for historical reasons, so that # people in areas not otherwise covered by the tz files could "zic -l" # to a timezone that was right for their area. These days, the # tz files cover almost all the inhabited world, and the only practical # need now for the entries that are not on UTC are for ships at sea # that cannot use POSIX TZ settings. # Starting with POSIX 1003.1-2001, the entries below are all # unnecessary as settings for the TZ environment variable. E.g., # instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. # # Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours # behind GMT but uses the completely misleading abbreviation "GMT". Zone Etc/GMT 0 - GMT Zone Etc/UTC 0 - UTC # The following link uses older naming conventions, # but it belongs here, not in the file 'backward', # as functions like gmtime load the "UTC" file to handle leap seconds properly. # We want this to work even on installations that omit the other older names. Link Etc/UTC UTC Link Etc/UTC Etc/Universal Link Etc/UTC Etc/Zulu Link Etc/GMT Etc/Greenwich Link Etc/GMT Etc/GMT-0 Link Etc/GMT Etc/GMT+0 Link Etc/GMT Etc/GMT0 # Be consistent with POSIX TZ settings in the Zone names, # even though this is the opposite of what many people expect. # POSIX has positive signs west of Greenwich, but many people expect # positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses # the abbreviation "-04" and corresponds to 4 hours behind UT # (i.e. west of Greenwich) even though many people would expect it to # mean 4 hours ahead of UT (i.e. east of Greenwich). # Earlier incarnations of this package were not POSIX-compliant, # and had lines such as # Zone GMT-12 -12 - GMT-1200 # We did not want things to change quietly if someone accustomed to the old # way does a # zic -l GMT-12 # so we moved the names into the Etc subdirectory. # Also, the time zone abbreviations are now compatible with %z.
