These days, the# tz files cover almost all the inhabited world, and the only practical# need now for the entries that are not on UTC are for ships at sea# that cannot use POSIX TZ settings.# Starting with POSIX 1003.1-2001, the entries below are all# unnecessary as settings for the TZ environment variable. E.g.,# instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'.## Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours# behind GMT but uses the completely misleading abbreviation "GMT".Zone Etc/GMT 0 - GMTZone Etc/UTC 0 - UTCZone Etc/UCT 0 - UCT# The following link uses older naming conventions,# but it belongs here, not in the file 'backward',# as functions like gmtime load the "GMT" file to handle leap seconds properly.# We want this to work even on installations that omit the other older names.Link Etc/GMT GMTLink Etc/UTC Etc/UniversalLink Etc/UTC Etc/ZuluLink Etc/GMT Etc/GreenwichLink Etc/GMT Etc/GMT-0Link Etc/GMT Etc/GMT+0Link Etc/GMT Etc/GMT0# Be consistent with POSIX TZ settings in the Zone names,# even though this is the opposite of what many people expect.# POSIX has positive signs west of Greenwich, but many people expect# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses# the abbreviation "-04" and corresponds to 4 hours behind UT# (i.e. west of Greenwich) even though many people would expect it to# mean 4 hours ahead of UT (i.e. east of Greenwich).# Earlier incarnations of this package were not POSIX-compliant,# and had lines such as# Zone GMT-12 -12 - GMT-1200# We did not want things to change quietly if someone accustomed to the old# way does a# zic -l GMT-12# so we moved the names into the Etc subdirectory.# Also, the time zone abbreviations are now compatible with %z.Zone Etc/GMT-14 14 - +14Zone Etc/GMT-13 13 - +13Zone Etc/GMT-12 12 - +12Zone Etc/GMT-11 11 - +11Zone Etc/GMT-10 10 - +10Zone Etc/GMT-9 9 - +09Zone Etc/GMT-8 8 - +08Zone Etc/GMT-7 7 - +07Zone Etc/GMT-6 6 - +06Zone Etc/GMT-5 5 - +05Zone Etc/GMT-4 4 - +04Zone Etc/GMT-3 3 - +03Zone Etc/GMT-2 2 - +02Zone Etc/GMT-1 1 - +01Zone Etc/GMT+1 -1 - -01Zone Etc/GMT+2 -2 - -02Zone Etc/GMT+3 -3 - -03Zone Etc/GMT+4 -4 - -04Zone Etc/GMT+5 -5 - -05Zone Etc/GMT+6 -6 - -06Zone Etc/GMT+7 -7 - -07Zone Etc/GMT+8 -8 - -08Zone Etc/GMT+9 -9 - -09Zone Etc/GMT+10 -10 - -10Zone Etc/GMT+11 -11 - -11Zone Etc/GMT+12 -12 - -12
