On such platforms these entries 10# can be useful if the timezone database is wrong or if a ship or 11# aircraft at sea is not in a timezone. 12 13# Starting with POSIX 1003.1-2001, the entries below are all 14# unnecessary as settings for the TZ environment variable. E.g., 15# instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. 16# 17# Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours 18# behind GMT but uses the completely misleading abbreviation "GMT". 19 20# The following zone is used by tzcode functions like gmtime, 21# which load the "UTC" file to handle seconds properly. 22Zone Etc/UTC 0 - UTC 23 24# Functions like gmtime load the "GMT" file to handle leap seconds properly. 25# Vanguard section, which works with most .zi parsers. 26#Zone GMT 0 - GMT 27# Rearguard section, for TZUpdater 2.3.2 and earlier. 28Zone Etc/GMT 0 - GMT 29 30# The following link uses older naming conventions, 31# but it belongs here, not in the file 'backward', 32# as it is needed for tzcode releases through 2022a, 33# where functions like gmtime load "GMT" instead of the "Etc/UTC". 34# We want this to work even on installations that omit 'backward'. 35Link Etc/GMT GMT 36# End of rearguard section. 37 38# Be consistent with POSIX TZ settings in the Zone names, 39# even though this is the opposite of what many people expect. 40# POSIX has positive signs west of Greenwich, but many people expect 41# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 42# the abbreviation "-04" and corresponds to 4 hours behind UT 43# (i.e. west of Greenwich) even though many people would expect it to 44# mean 4 hours ahead of UT (i.e. east of Greenwich). 45 46# Earlier incarnations of this package were not POSIX-compliant, 47# and had lines such as 48# Zone GMT-12 -12 - GMT-1200 49# We did not want things to change quietly if someone accustomed to the old 50# way does a 51# zic -l GMT-12 52# so we moved the names into the Etc subdirectory. 53# Also, the time zone abbreviations are now compatible with %z. 54 55# There is no "Etc/Unknown" entry, as CLDR says that "Etc/Unknown" 56# corresponds to an unknown or invalid time zone, and things would get 57# confusing if Etc/Unknown were made valid here. 58 59Zone Etc/GMT-14 14 - %z 60Zone Etc/GMT-13 13 - %z 61Zone Etc/GMT-12 12 - %z 62Zone Etc/GMT-11 11 - %z 63Zone Etc/GMT-10 10 - %z 64Zone Etc/GMT-9 9 - %z 65Zone Etc/GMT-8 8 - %z 66Zone Etc/GMT-7 7 - %z 67Zone Etc/GMT-6 6 - %z 68Zone Etc/GMT-5 5 - %z 69Zone Etc/GMT-4 4 - %z 70Zone Etc/GMT-3 3 - %z 71Zone Etc/GMT-2 2 - %z 72Zone Etc/GMT-1 1 - %z 73Zone Etc/GMT+1 -1 - %z 74Zone Etc/GMT+2 -2 - %z 75Zone Etc/GMT+3 -3 - %z 76Zone Etc/GMT+4 -4 - %z 77Zone Etc/GMT+5 -5 - %z 78Zone Etc/GMT+6 -6 - %z 79Zone Etc/GMT+7 -7 - %z 80Zone Etc/GMT+8 -8 - %z 81Zone Etc/GMT+9 -9 - %z 82Zone Etc/GMT+10 -10 - %z 83Zone Etc/GMT+11 -11 - %z 84Zone Etc/GMT+12 -12 - %z 85
