These days, the 91315084cSEdwin Groothuis# tz files cover almost all the inhabited world, and the only practical 101315084cSEdwin Groothuis# need now for the entries that are not on UTC are for ships at sea 111315084cSEdwin Groothuis# that cannot use POSIX TZ settings. 121315084cSEdwin Groothuis 131315084cSEdwin GroothuisZone Etc/GMT 0 - GMT 141315084cSEdwin GroothuisZone Etc/UTC 0 - UTC 151315084cSEdwin GroothuisZone Etc/UCT 0 - UCT 161315084cSEdwin Groothuis 171315084cSEdwin Groothuis# The following link uses older naming conventions, 181315084cSEdwin Groothuis# but it belongs here, not in the file `backward', 191315084cSEdwin Groothuis# as functions like gmtime load the "UTC" file to handle leap seconds properly. 201315084cSEdwin Groothuis# We want this to work even on installations that omit the other older names. 211315084cSEdwin GroothuisLink Etc/UTC UTC 221315084cSEdwin Groothuis 231315084cSEdwin GroothuisLink Etc/UTC Etc/Universal 241315084cSEdwin GroothuisLink Etc/UTC Etc/Zulu 251315084cSEdwin Groothuis 261315084cSEdwin GroothuisLink Etc/GMT Etc/Greenwich 271315084cSEdwin GroothuisLink Etc/GMT Etc/GMT-0 281315084cSEdwin GroothuisLink Etc/GMT Etc/GMT+0 291315084cSEdwin GroothuisLink Etc/GMT Etc/GMT0 301315084cSEdwin Groothuis 311315084cSEdwin Groothuis# We use POSIX-style signs in the Zone names and the output abbreviations, 321315084cSEdwin Groothuis# even though this is the opposite of what many people expect. 331315084cSEdwin Groothuis# POSIX has positive signs west of Greenwich, but many people expect 341315084cSEdwin Groothuis# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 351315084cSEdwin Groothuis# the abbreviation "GMT+4" and corresponds to 4 hours behind UTC 361315084cSEdwin Groothuis# (i.e. west of Greenwich) even though many people would expect it to 371315084cSEdwin Groothuis# mean 4 hours ahead of UTC (i.e. east of Greenwich). 381315084cSEdwin Groothuis# 391315084cSEdwin Groothuis# In the draft 5 of POSIX 1003.1-200x, the angle bracket notation 401315084cSEdwin Groothuis# (which is not yet supported by the tz code) allows for 411315084cSEdwin Groothuis# TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to 421315084cSEdwin Groothuis# ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected 431315084cSEdwin Groothuis# offset is kept within the angle bracket (and is used for display) 441315084cSEdwin Groothuis# while the POSIX sign is kept outside the angle bracket (and is used 451315084cSEdwin Groothuis# for calculation). 461315084cSEdwin Groothuis# 471315084cSEdwin Groothuis# Do not use a TZ setting like TZ='GMT+4', which is four hours behind 481315084cSEdwin Groothuis# GMT but uses the completely misleading abbreviation "GMT". 491315084cSEdwin Groothuis 501315084cSEdwin Groothuis# Earlier incarnations of this package were not POSIX-compliant, 511315084cSEdwin Groothuis# and had lines such as 521315084cSEdwin Groothuis# Zone GMT-12 -12 - GMT-1200 531315084cSEdwin Groothuis# We did not want things to change quietly if someone accustomed to the old 541315084cSEdwin Groothuis# way does a 551315084cSEdwin Groothuis# zic -l GMT-12 561315084cSEdwin Groothuis# so we moved the names into the Etc subdirectory. 571315084cSEdwin Groothuis 581315084cSEdwin GroothuisZone Etc/GMT-14 14 - GMT-14 # 14 hours ahead of GMT 591315084cSEdwin GroothuisZone Etc/GMT-13 13 - GMT-13 601315084cSEdwin GroothuisZone Etc/GMT-12 12 - GMT-12 611315084cSEdwin GroothuisZone Etc/GMT-11 11 - GMT-11 621315084cSEdwin GroothuisZone Etc/GMT-10 10 - GMT-10 631315084cSEdwin GroothuisZone Etc/GMT-9 9 - GMT-9 641315084cSEdwin GroothuisZone Etc/GMT-8 8 - GMT-8 651315084cSEdwin GroothuisZone Etc/GMT-7 7 - GMT-7 661315084cSEdwin GroothuisZone Etc/GMT-6 6 - GMT-6 671315084cSEdwin GroothuisZone Etc/GMT-5 5 - GMT-5 681315084cSEdwin GroothuisZone Etc/GMT-4 4 - GMT-4 691315084cSEdwin GroothuisZone Etc/GMT-3 3 - GMT-3 701315084cSEdwin GroothuisZone Etc/GMT-2 2 - GMT-2 711315084cSEdwin GroothuisZone Etc/GMT-1 1 - GMT-1 721315084cSEdwin GroothuisZone Etc/GMT+1 -1 - GMT+1 731315084cSEdwin GroothuisZone Etc/GMT+2 -2 - GMT+2 741315084cSEdwin GroothuisZone Etc/GMT+3 -3 - GMT+3 751315084cSEdwin GroothuisZone Etc/GMT+4 -4 - GMT+4 761315084cSEdwin GroothuisZone Etc/GMT+5 -5 - GMT+5 771315084cSEdwin GroothuisZone Etc/GMT+6 -6 - GMT+6 781315084cSEdwin GroothuisZone Etc/GMT+7 -7 - GMT+7 791315084cSEdwin GroothuisZone Etc/GMT+8 -8 - GMT+8 801315084cSEdwin GroothuisZone Etc/GMT+9 -9 - GMT+9 811315084cSEdwin GroothuisZone Etc/GMT+10 -10 - GMT+10 821315084cSEdwin GroothuisZone Etc/GMT+11 -11 - GMT+11 831315084cSEdwin GroothuisZone Etc/GMT+12 -12 - GMT+12 84
