1# <pre> 2# This file is in the public domain, so clarified as of 3# 2009-05-17 by Arthur David Olson. 4 5# These entries are mostly present for historical reasons, so that 6# people in areas not otherwise covered by the tz files could "zic -l" 7# to a time zone that was right for their area. These days, the 8# tz files cover almost all the inhabited world, and the only practical 9# need now for the entries that are not on UTC are for ships at sea 10# that cannot use POSIX TZ settings. 11 12Zone Etc/GMT 0 - GMT 13Zone Etc/UTC 0 - UTC 14Zone Etc/UCT 0 - UCT 15 16# The following link uses older naming conventions, 17# but it belongs here, not in the file `backward', 18# as functions like gmtime load the "GMT" file to handle leap seconds properly. 19# We want this to work even on installations that omit the other older names. 20Link Etc/GMT GMT 21 22Link Etc/UTC Etc/Universal 23Link Etc/UTC Etc/Zulu 24 25Link Etc/GMT Etc/Greenwich 26Link Etc/GMT Etc/GMT-0 27Link Etc/GMT Etc/GMT+0 28Link Etc/GMT Etc/GMT0 29 30# We use POSIX-style signs in the Zone names and the output abbreviations, 31# even though this is the opposite of what many people expect. 32# POSIX has positive signs west of Greenwich, but many people expect 33# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 34# the abbreviation "GMT+4" and corresponds to 4 hours behind UT 35# (i.e. west of Greenwich) even though many people would expect it to 36# mean 4 hours ahead of UT (i.e. east of Greenwich). 37# 38# In the draft 5 of POSIX 1003.1-200x, the angle bracket notation allows for 39# TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to 40# ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected 41# offset is kept within the angle bracket (and is used for display) 42# while the POSIX sign is kept outside the angle bracket (and is used 43# for calculation). 44# 45# Do not use a TZ setting like TZ='GMT+4', which is four hours behind 46# GMT but uses the completely misleading abbreviation "GMT". 47 48# Earlier incarnations of this package were not POSIX-compliant, 49# and had lines such as 50# Zone GMT-12 -12 - GMT-1200 51# We did not want things to change quietly if someone accustomed to the old 52# way does a 53# zic -l GMT-12 54# so we moved the names into the Etc subdirectory. 55 56Zone Etc/GMT-14 14 - GMT-14 # 14 hours ahead of GMT 57Zone Etc/GMT-13 13 - GMT-13 58Zone Etc/GMT-12 12 - GMT-12 59Zone Etc/GMT-11 11 - GMT-11 60Zone Etc/GMT-10 10 - GMT-10 61Zone Etc/GMT-9 9 - GMT-9 62Zone Etc/GMT-8 8 - GMT-8 63Zone Etc/GMT-7 7 - GMT-7 64Zone Etc/GMT-6 6 - GMT-6 65Zone Etc/GMT-5 5 - GMT-5 66Zone Etc/GMT-4 4 - GMT-4 67Zone Etc/GMT-3 3 - GMT-3 68Zone Etc/GMT-2 2 - GMT-2 69Zone Etc/GMT-1 1 - GMT-1 70Zone Etc/GMT+1 -1 - GMT+1 71Zone Etc/GMT+2 -2 - GMT+2 72Zone Etc/GMT+3 -3 - GMT+3 73Zone Etc/GMT+4 -4 - GMT+4 74Zone Etc/GMT+5 -5 - GMT+5 75Zone Etc/GMT+6 -6 - GMT+6 76Zone Etc/GMT+7 -7 - GMT+7 77Zone Etc/GMT+8 -8 - GMT+8 78Zone Etc/GMT+9 -9 - GMT+9 79Zone Etc/GMT+10 -10 - GMT+10 80Zone Etc/GMT+11 -11 - GMT+11 81Zone Etc/GMT+12 -12 - GMT+12 82
