These days, the 92386db68SMarcel Telka# tz files cover almost all the inhabited world, and the only practical 102386db68SMarcel Telka# need now for the entries that are not on UTC are for ships at sea 112386db68SMarcel Telka# that cannot use POSIX TZ settings. 122386db68SMarcel Telka 132386db68SMarcel Telka# Starting with POSIX 1003.1-2001, the entries below are all 142386db68SMarcel Telka# unnecessary as settings for the TZ environment variable. E.g., 152386db68SMarcel Telka# instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. 162386db68SMarcel Telka# 172386db68SMarcel Telka# Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours 182386db68SMarcel Telka# behind GMT but uses the completely misleading abbreviation "GMT". 192386db68SMarcel Telka 202386db68SMarcel TelkaZone Etc/GMT 0 - GMT 212386db68SMarcel TelkaZone Etc/UTC 0 - UTC 222386db68SMarcel TelkaZone Etc/UCT 0 - UCT 232386db68SMarcel Telka 242386db68SMarcel Telka# The following link uses older naming conventions, 252386db68SMarcel Telka# but it belongs here, not in the file 'backward', 262386db68SMarcel Telka# as functions like gmtime load the "GMT" file to handle leap seconds properly. 272386db68SMarcel Telka# We want this to work even on installations that omit the other older names. 282386db68SMarcel TelkaLink Etc/GMT GMT 292386db68SMarcel Telka 302386db68SMarcel TelkaLink Etc/UTC Etc/Universal 312386db68SMarcel TelkaLink Etc/UTC Etc/Zulu 322386db68SMarcel Telka 332386db68SMarcel TelkaLink Etc/GMT Etc/Greenwich 342386db68SMarcel TelkaLink Etc/GMT Etc/GMT-0 352386db68SMarcel TelkaLink Etc/GMT Etc/GMT+0 362386db68SMarcel TelkaLink Etc/GMT Etc/GMT0 372386db68SMarcel Telka 382386db68SMarcel Telka# Be consistent with POSIX TZ settings in the Zone names, 392386db68SMarcel Telka# even though this is the opposite of what many people expect. 402386db68SMarcel Telka# POSIX has positive signs west of Greenwich, but many people expect 412386db68SMarcel Telka# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 422386db68SMarcel Telka# the abbreviation "-04" and corresponds to 4 hours behind UT 432386db68SMarcel Telka# (i.e. west of Greenwich) even though many people would expect it to 442386db68SMarcel Telka# mean 4 hours ahead of UT (i.e. east of Greenwich). 452386db68SMarcel Telka 462386db68SMarcel Telka# Earlier incarnations of this package were not POSIX-compliant, 472386db68SMarcel Telka# and had lines such as 482386db68SMarcel Telka# Zone GMT-12 -12 - GMT-1200 492386db68SMarcel Telka# We did not want things to change quietly if someone accustomed to the old 502386db68SMarcel Telka# way does a 512386db68SMarcel Telka# zic -l GMT-12 522386db68SMarcel Telka# so we moved the names into the Etc subdirectory. 532386db68SMarcel Telka# Also, the time zone abbreviations are now compatible with %z. 542386db68SMarcel Telka 552386db68SMarcel TelkaZone Etc/GMT-14 14 - +14 562386db68SMarcel TelkaZone Etc/GMT-13 13 - +13 572386db68SMarcel TelkaZone Etc/GMT-12 12 - +12 582386db68SMarcel TelkaZone Etc/GMT-11 11 - +11 592386db68SMarcel TelkaZone Etc/GMT-10 10 - +10 602386db68SMarcel TelkaZone Etc/GMT-9 9 - +09 612386db68SMarcel TelkaZone Etc/GMT-8 8 - +08 622386db68SMarcel TelkaZone Etc/GMT-7 7 - +07 632386db68SMarcel TelkaZone Etc/GMT-6 6 - +06 642386db68SMarcel TelkaZone Etc/GMT-5 5 - +05 652386db68SMarcel TelkaZone Etc/GMT-4 4 - +04 662386db68SMarcel TelkaZone Etc/GMT-3 3 - +03 672386db68SMarcel TelkaZone Etc/GMT-2 2 - +02 682386db68SMarcel TelkaZone Etc/GMT-1 1 - +01 692386db68SMarcel TelkaZone Etc/GMT+1 -1 - -01 702386db68SMarcel TelkaZone Etc/GMT+2 -2 - -02 712386db68SMarcel TelkaZone Etc/GMT+3 -3 - -03 722386db68SMarcel TelkaZone Etc/GMT+4 -4 - -04 732386db68SMarcel TelkaZone Etc/GMT+5 -5 - -05 742386db68SMarcel TelkaZone Etc/GMT+6 -6 - -06 752386db68SMarcel TelkaZone Etc/GMT+7 -7 - -07 762386db68SMarcel TelkaZone Etc/GMT+8 -8 - -08 772386db68SMarcel TelkaZone Etc/GMT+9 -9 - -09 782386db68SMarcel TelkaZone Etc/GMT+10 -10 - -10 792386db68SMarcel TelkaZone Etc/GMT+11 -11 - -11 802386db68SMarcel TelkaZone Etc/GMT+12 -12 - -12 81
