On such platforms these entries +# can be useful if the timezone database is wrong or if a ship or +# aircraft at sea is not in a timezone. + +# 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". + +# The following zone is used by tzcode functions like gmtime, +# which load the "UTC" file to handle seconds properly. +Zone Etc/UTC 0 - UTC + +# Functions like gmtime load the "GMT" file to handle leap seconds properly. +# Vanguard section, which works with most .zi parsers. +#Zone GMT 0 - GMT +# Rearguard section, for TZUpdater 2.3.2 and earlier. +Zone Etc/GMT 0 - GMT + +# The following link uses older naming conventions, +# but it belongs here, not in the file 'backward', +# as it is needed for tzcode releases through 2022a, +# where functions like gmtime load "GMT" instead of the "Etc/UTC". +# We want this to work even on installations that omit 'backward'. +Link Etc/GMT GMT +# End of rearguard section. + +# 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 - +14 +Zone Etc/GMT-13 13 - +13 +Zone Etc/GMT-12 12 - +12 +Zone Etc/GMT-11 11 - +11 +Zone Etc/GMT-10 10 - +10 +Zone Etc/GMT-9 9 - +09 +Zone Etc/GMT-8 8 - +08 +Zone Etc/GMT-7 7 - +07 +Zone Etc/GMT-6 6 - +06 +Zone Etc/GMT-5 5 - +05 +Zone Etc/GMT-4 4 - +04 +Zone Etc/GMT-3 3 - +03 +Zone Etc/GMT-2 2 - +02 +Zone Etc/GMT-1 1 - +01 +Zone Etc/GMT+1 -1 - -01 +Zone Etc/GMT+2 -2 - -02 +Zone Etc/GMT+3 -3 - -03 +Zone Etc/GMT+4 -4 - -04 +Zone Etc/GMT+5 -5 - -05 +Zone Etc/GMT+6 -6 - -06 +Zone Etc/GMT+7 -7 - -07 +Zone Etc/GMT+8 -8 - -08 +Zone Etc/GMT+9 -9 - -09 +Zone Etc/GMT+10 -10 - -10 +Zone Etc/GMT+11 -11 - -11 +Zone Etc/GMT+12 -12 - -12 |
