These days, the 9503609a9SYuri Pankov# tz files cover almost all the inhabited world, and the only practical 10503609a9SYuri Pankov# need now for the entries that are not on UTC are for ships at sea 11503609a9SYuri Pankov# that cannot use POSIX TZ settings. 12503609a9SYuri Pankov 13503609a9SYuri Pankov# Starting with POSIX 1003.1-2001, the entries below are all 14503609a9SYuri Pankov# unnecessary as settings for the TZ environment variable. E.g., 15503609a9SYuri Pankov# instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. 16503609a9SYuri Pankov# 17503609a9SYuri Pankov# Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours 18503609a9SYuri Pankov# behind GMT but uses the completely misleading abbreviation "GMT". 19503609a9SYuri Pankov 20503609a9SYuri PankovZone Etc/GMT 0 - GMT 21503609a9SYuri PankovZone Etc/UTC 0 - UTC 22503609a9SYuri PankovZone Etc/UCT 0 - UCT 23503609a9SYuri Pankov 24503609a9SYuri Pankov# The following link uses older naming conventions, 25503609a9SYuri Pankov# but it belongs here, not in the file 'backward', 26503609a9SYuri Pankov# as functions like gmtime load the "GMT" file to handle leap seconds properly. 27503609a9SYuri Pankov# We want this to work even on installations that omit the other older names. 28503609a9SYuri PankovLink Etc/GMT GMT 29503609a9SYuri Pankov 30503609a9SYuri PankovLink Etc/UTC Etc/Universal 31503609a9SYuri PankovLink Etc/UTC Etc/Zulu 32503609a9SYuri Pankov 33503609a9SYuri PankovLink Etc/GMT Etc/Greenwich 34503609a9SYuri PankovLink Etc/GMT Etc/GMT-0 35503609a9SYuri PankovLink Etc/GMT Etc/GMT+0 36503609a9SYuri PankovLink Etc/GMT Etc/GMT0 37503609a9SYuri Pankov 38503609a9SYuri Pankov# Be consistent with POSIX TZ settings in the Zone names, 39503609a9SYuri Pankov# even though this is the opposite of what many people expect. 40503609a9SYuri Pankov# POSIX has positive signs west of Greenwich, but many people expect 41503609a9SYuri Pankov# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 42503609a9SYuri Pankov# the abbreviation "-04" and corresponds to 4 hours behind UT 43503609a9SYuri Pankov# (i.e. west of Greenwich) even though many people would expect it to 44503609a9SYuri Pankov# mean 4 hours ahead of UT (i.e. east of Greenwich). 45503609a9SYuri Pankov 46503609a9SYuri Pankov# Earlier incarnations of this package were not POSIX-compliant, 47503609a9SYuri Pankov# and had lines such as 48503609a9SYuri Pankov# Zone GMT-12 -12 - GMT-1200 49503609a9SYuri Pankov# We did not want things to change quietly if someone accustomed to the old 50503609a9SYuri Pankov# way does a 51503609a9SYuri Pankov# zic -l GMT-12 52503609a9SYuri Pankov# so we moved the names into the Etc subdirectory. 53503609a9SYuri Pankov# Also, the time zone abbreviations are now compatible with %z. 54503609a9SYuri Pankov 55503609a9SYuri PankovZone Etc/GMT-14 14 - +14 56503609a9SYuri PankovZone Etc/GMT-13 13 - +13 57503609a9SYuri PankovZone Etc/GMT-12 12 - +12 58503609a9SYuri PankovZone Etc/GMT-11 11 - +11 59503609a9SYuri PankovZone Etc/GMT-10 10 - +10 60503609a9SYuri PankovZone Etc/GMT-9 9 - +09 61503609a9SYuri PankovZone Etc/GMT-8 8 - +08 62503609a9SYuri PankovZone Etc/GMT-7 7 - +07 63503609a9SYuri PankovZone Etc/GMT-6 6 - +06 64503609a9SYuri PankovZone Etc/GMT-5 5 - +05 65503609a9SYuri PankovZone Etc/GMT-4 4 - +04 66503609a9SYuri PankovZone Etc/GMT-3 3 - +03 67503609a9SYuri PankovZone Etc/GMT-2 2 - +02 68503609a9SYuri PankovZone Etc/GMT-1 1 - +01 69503609a9SYuri PankovZone Etc/GMT+1 -1 - -01 70503609a9SYuri PankovZone Etc/GMT+2 -2 - -02 71503609a9SYuri PankovZone Etc/GMT+3 -3 - -03 72503609a9SYuri PankovZone Etc/GMT+4 -4 - -04 73503609a9SYuri PankovZone Etc/GMT+5 -5 - -05 74503609a9SYuri PankovZone Etc/GMT+6 -6 - -06 75503609a9SYuri PankovZone Etc/GMT+7 -7 - -07 76503609a9SYuri PankovZone Etc/GMT+8 -8 - -08 77503609a9SYuri PankovZone Etc/GMT+9 -9 - -09 78503609a9SYuri PankovZone Etc/GMT+10 -10 - -10 79503609a9SYuri PankovZone Etc/GMT+11 -11 - -11 80503609a9SYuri PankovZone Etc/GMT+12 -12 - -12 81
