1149511Swollman# @(#)etcetera 7.12 22744Swollman 320091Swollman# These entries are mostly present for historical reasons, so that 420091Swollman# people in areas not otherwise covered by the tz files could "zic -l" 520091Swollman# to a time zone that was right for their area. These days, the 6149511Swollman# tz files cover almost all the inhabited world, and the only practical 7149511Swollman# need now for the entries that are not on UTC are for ships at sea 8149511Swollman# that cannot use POSIX TZ settings. 92744Swollman 102744SwollmanZone Etc/GMT 0 - GMT 1120091SwollmanZone Etc/UTC 0 - UTC 1220091SwollmanZone Etc/UCT 0 - UCT 1320091Swollman 1443009Swollman# The following link uses older naming conventions, 1543009Swollman# but it belongs here, not in the file `backward', 1643009Swollman# as functions like gmtime load the "GMT" file to handle leap seconds properly. 1743009Swollman# We want this to work even on installations that omit the other older names. 1843009SwollmanLink Etc/GMT GMT 1943009Swollman 2020091SwollmanLink Etc/UTC Etc/Universal 2120091SwollmanLink Etc/UTC Etc/Zulu 2220091Swollman 232744SwollmanLink Etc/GMT Etc/Greenwich 242744SwollmanLink Etc/GMT Etc/GMT-0 252744SwollmanLink Etc/GMT Etc/GMT+0 262744SwollmanLink Etc/GMT Etc/GMT0 272744Swollman 2875264Swollman# We use POSIX-style signs in the Zone names and the output abbreviations, 2975264Swollman# even though this is the opposite of what many people expect. 3075264Swollman# POSIX has positive signs west of Greenwich, but many people expect 3175264Swollman# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 3275264Swollman# the abbreviation "GMT+4" and corresponds to 4 hours behind UTC 3375264Swollman# (i.e. west of Greenwich) even though many people would expect it to 3475264Swollman# mean 4 hours ahead of UTC (i.e. east of Greenwich). 3575264Swollman# 3675264Swollman# In the draft 5 of POSIX 1003.1-200x, the angle bracket notation 3775264Swollman# (which is not yet supported by the tz code) allows for 3875264Swollman# TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to 3975264Swollman# ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected 4075264Swollman# offset is kept within the angle bracket (and is used for display) 4175264Swollman# while the POSIX sign is kept outside the angle bracket (and is used 4275264Swollman# for calculation). 4375264Swollman# 4475264Swollman# Do not use a TZ setting like TZ='GMT+4', which is four hours behind 4575264Swollman# GMT but uses the completely misleading abbreviation "GMT". 462744Swollman 472744Swollman# Earlier incarnations of this package were not POSIX-compliant, 482744Swollman# and had lines such as 492744Swollman# Zone GMT-12 -12 - GMT-1200 502744Swollman# We did not want things to change quietly if someone accustomed to the old 512744Swollman# way does a 522744Swollman# zic -l GMT-12 532744Swollman# so we moved the names into the Etc subdirectory. 542744Swollman 5514709SwollmanZone Etc/GMT-14 14 - GMT-14 # 14 hours ahead of GMT 5614709SwollmanZone Etc/GMT-13 13 - GMT-13 572744SwollmanZone Etc/GMT-12 12 - GMT-12 582744SwollmanZone Etc/GMT-11 11 - GMT-11 592744SwollmanZone Etc/GMT-10 10 - GMT-10 602744SwollmanZone Etc/GMT-9 9 - GMT-9 612744SwollmanZone Etc/GMT-8 8 - GMT-8 622744SwollmanZone Etc/GMT-7 7 - GMT-7 632744SwollmanZone Etc/GMT-6 6 - GMT-6 642744SwollmanZone Etc/GMT-5 5 - GMT-5 652744SwollmanZone Etc/GMT-4 4 - GMT-4 662744SwollmanZone Etc/GMT-3 3 - GMT-3 672744SwollmanZone Etc/GMT-2 2 - GMT-2 682744SwollmanZone Etc/GMT-1 1 - GMT-1 692744SwollmanZone Etc/GMT+1 -1 - GMT+1 702744SwollmanZone Etc/GMT+2 -2 - GMT+2 712744SwollmanZone Etc/GMT+3 -3 - GMT+3 722744SwollmanZone Etc/GMT+4 -4 - GMT+4 732744SwollmanZone Etc/GMT+5 -5 - GMT+5 742744SwollmanZone Etc/GMT+6 -6 - GMT+6 752744SwollmanZone Etc/GMT+7 -7 - GMT+7 762744SwollmanZone Etc/GMT+8 -8 - GMT+8 772744SwollmanZone Etc/GMT+9 -9 - GMT+9 782744SwollmanZone Etc/GMT+10 -10 - GMT+10 792744SwollmanZone Etc/GMT+11 -11 - GMT+11 802744SwollmanZone Etc/GMT+12 -12 - GMT+12 81
