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 19Zone Etc/GMT 0 - GMT 20Zone Etc/UTC 0 - UTC 21 22# The following link uses older naming conventions, 23# but it belongs here, not in the file 'backward', 24# as functions like gmtime load the "UTC" file to handle leap seconds properly. 25# We want this to work even on installations that omit the other older names. 26Link Etc/UTC UTC 27 28Link Etc/UTC Etc/Universal 29Link Etc/UTC Etc/Zulu 30 31Link Etc/GMT Etc/Greenwich 32Link Etc/GMT Etc/GMT-0 33Link Etc/GMT Etc/GMT+0 34Link Etc/GMT Etc/GMT0 35 36# Be consistent with POSIX TZ settings in the Zone names, 37# even though this is the opposite of what many people expect. 38# POSIX has positive signs west of Greenwich, but many people expect 39# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 40# the abbreviation "-04" and corresponds to 4 hours behind UT 41# (i.e. west of Greenwich) even though many people would expect it to 42# mean 4 hours ahead of UT (i.e. east of Greenwich). 43 44# Earlier incarnations of this package were not POSIX-compliant, 45# and had lines such as 46# Zone GMT-12 -12 - GMT-1200 47# We did not want things to change quietly if someone accustomed to the old 48# way does a 49# zic -l GMT-12 50# so we moved the names into the Etc subdirectory. 51# Also, the time zone abbreviations are now compatible with %z. 52 53Zone Etc/GMT-14 14 - +14 54Zone Etc/GMT-13 13 - +13 55Zone Etc/GMT-12 12 - +12 56Zone Etc/GMT-11 11 - +11 57Zone Etc/GMT-10 10 - +10 58Zone Etc/GMT-9 9 - +09 59Zone Etc/GMT-8 8 - +08 60Zone Etc/GMT-7 7 - +07 61Zone Etc/GMT-6 6 - +06 62Zone Etc/GMT-5 5 - +05 63Zone Etc/GMT-4 4 - +04 64Zone Etc/GMT-3 3 - +03 65Zone Etc/GMT-2 2 - +02 66Zone Etc/GMT-1 1 - +01 67Zone Etc/GMT+1 -1 - -01 68Zone Etc/GMT+2 -2 - -02 69Zone Etc/GMT+3 -3 - -03 70Zone Etc/GMT+4 -4 - -04 71Zone Etc/GMT+5 -5 - -05 72Zone Etc/GMT+6 -6 - -06 73Zone Etc/GMT+7 -7 - -07 74Zone Etc/GMT+8 -8 - -08 75Zone Etc/GMT+9 -9 - -09 76Zone Etc/GMT+10 -10 - -10 77Zone Etc/GMT+11 -11 - -11 78Zone Etc/GMT+12 -12 - -12 79
