1# tzdb data for ships at sea and other miscellany 2 3# This file is in the public domain, so clarified as of 4# 2009-05-17 by Arthur David Olson. 5 6# These entries are for uses not otherwise covered by the tz database. 7# Their main practical use is for platforms like Android that lack 8# support for POSIX-style TZ strings. On such platforms these entries 9# can be useful if the timezone database is wrong or if a ship or 10# aircraft at sea is not in a timezone. 11 12# Starting with POSIX 1003.1-2001, the entries below are all 13# unnecessary as settings for the TZ environment variable. E.g., 14# instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. 15# 16# Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours 17# behind GMT but uses the completely misleading abbreviation "GMT". 18 19# The following zone is used by tzcode functions like gmtime, 20# which load the "UTC" file to handle seconds properly. 21Zone Etc/UTC 0 - UTC 22 23# Functions like gmtime load the "GMT" file to handle leap seconds properly. 24# Vanguard section, which works with most .zi parsers. 25#Zone GMT 0 - GMT 26# Rearguard section, for TZUpdater 2.3.2 and earlier. 27Zone Etc/GMT 0 - GMT 28 29# The following link uses older naming conventions, 30# but it belongs here, not in the file 'backward', 31# as it is needed for tzcode releases through 2022a, 32# where functions like gmtime load "GMT" instead of the "Etc/UTC". 33# We want this to work even on installations that omit 'backward'. 34Link Etc/GMT GMT 35# End of rearguard section. 36 37# Be consistent with POSIX TZ settings in the Zone names, 38# even though this is the opposite of what many people expect. 39# POSIX has positive signs west of Greenwich, but many people expect 40# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 41# the abbreviation "-04" and corresponds to 4 hours behind UT 42# (i.e. west of Greenwich) even though many people would expect it to 43# mean 4 hours ahead of UT (i.e. east of Greenwich). 44 45# Earlier incarnations of this package were not POSIX-compliant, 46# and had lines such as 47# Zone GMT-12 -12 - GMT-1200 48# We did not want things to change quietly if someone accustomed to the old 49# way does a 50# zic -l GMT-12 51# so we moved the names into the Etc subdirectory. 52# Also, the time zone abbreviations are now compatible with %z. 53 54Zone Etc/GMT-14 14 - +14 55Zone Etc/GMT-13 13 - +13 56Zone Etc/GMT-12 12 - +12 57Zone Etc/GMT-11 11 - +11 58Zone Etc/GMT-10 10 - +10 59Zone Etc/GMT-9 9 - +09 60Zone Etc/GMT-8 8 - +08 61Zone Etc/GMT-7 7 - +07 62Zone Etc/GMT-6 6 - +06 63Zone Etc/GMT-5 5 - +05 64Zone Etc/GMT-4 4 - +04 65Zone Etc/GMT-3 3 - +03 66Zone Etc/GMT-2 2 - +02 67Zone Etc/GMT-1 1 - +01 68Zone Etc/GMT+1 -1 - -01 69Zone Etc/GMT+2 -2 - -02 70Zone Etc/GMT+3 -3 - -03 71Zone Etc/GMT+4 -4 - -04 72Zone Etc/GMT+5 -5 - -05 73Zone Etc/GMT+6 -6 - -06 74Zone Etc/GMT+7 -7 - -07 75Zone Etc/GMT+8 -8 - -08 76Zone Etc/GMT+9 -9 - -09 77Zone Etc/GMT+10 -10 - -10 78Zone Etc/GMT+11 -11 - -11 79Zone Etc/GMT+12 -12 - -12 80
