- # 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 for uses not otherwise covered by the tz database.
- # Their main practical use is for platforms like Android that lack
- # support for POSIX-style TZ strings. On such platforms these entries
- # can be useful if the timezone database is wrong or if a ship or
- # aircraft at sea is not in a timezone.
- # 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".
- # The following zone is used by tzcode functions like gmtime,
- # which load the "UTC" file to handle seconds properly.
- Zone Etc/UTC 0 - UTC
- # Functions like gmtime load the "GMT" file to handle leap seconds properly.
- # Vanguard section, which works with most .zi parsers.
- #Zone GMT 0 - GMT
- # Rearguard section, for TZUpdater 2.3.2 and earlier.
- Zone Etc/GMT 0 - GMT
- # The following link uses older naming conventions,
- # but it belongs here, not in the file 'backward',
- # as it is needed for tzcode releases through 2022a,
- # where functions like gmtime load "GMT" instead of the "Etc/UTC".
- # We want this to work even on installations that omit 'backward'.
- Link Etc/GMT GMT
- # End of rearguard section.
- # 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.
