- # 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 time zone 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.

- Zone Etc/UTC 0 - UTC
- Zone Etc/UCT 0 - UCT
- # The following link uses older naming conventions,
- # but it belongs here, not in the file 'backward',
- # as functions like gmtime load the "GMT" file to handle leap seconds properly.
- # We want this to work even on installations that omit the other older names.

- # We use POSIX-style signs in the Zone names and the output abbreviations,
- # 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 "GMT+4" 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).
- #
- # In the draft 5 of POSIX 1003.1-200x, the angle bracket notation allows for
- # TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to
- # ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected
- # offset is kept within the angle bracket (and is used for display)
- # while the POSIX sign is kept outside the angle bracket (and is used
- # for calculation).
- #
- # Do not use a TZ setting like TZ='GMT+4', which is four hours behind
- # GMT but uses the completely misleading abbreviation "GMT".
- # 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.
