1627N/A# This file is in the public domain, so clarified as of
1627N/A# 2009-05-17 by Arthur David Olson.
0N/A# These entries are mostly present for historical reasons, so that
0N/A# people in areas not otherwise covered by the tz files could "zic -l"
0N/A# to a time zone that was right for their area. These days, the
0N/A# tz files cover almost all the inhabited world, and the only practical
0N/A# need now for the entries that are not on UTC are for ships at sea
0N/A# that cannot use POSIX TZ settings.
0N/A# The following link uses older naming conventions,
0N/A# but it belongs here, not in the file `backward',
0N/A# as functions like gmtime load the "GMT" file to handle leap seconds properly.
0N/A# We want this to work even on installations that omit the other older names.
0N/A# We use POSIX-style signs in the Zone names and the output abbreviations,
0N/A# even though this is the opposite of what many people expect.
0N/A# POSIX has positive signs west of Greenwich, but many people expect
0N/A# positive signs east of Greenwich. For example, TZ='
Etc/GMT+4' uses
0N/A# the abbreviation "GMT+4" and corresponds to 4 hours behind UTC
0N/A# (
i.e. west of Greenwich) even though many people would expect it to
0N/A# mean 4 hours ahead of UTC (
i.e. east of Greenwich).
3732N/A# In the draft 5 of POSIX 1003.1-200x, the angle bracket notation allows for
0N/A# TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to
0N/A# ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected
0N/A# offset is kept within the angle bracket (and is used for display)
0N/A# while the POSIX sign is kept outside the angle bracket (and is used
0N/A# Do not use a TZ setting like TZ='GMT+4', which is four hours behind
0N/A# GMT but uses the completely misleading abbreviation "GMT".
0N/A# Earlier incarnations of this package were not POSIX-compliant,
0N/A# and had lines such as
0N/A# Zone GMT-12 -12 - GMT-1200
0N/A# We did not want things to change quietly if someone accustomed to the old
0N/A# so we moved the names into the Etc subdirectory.
