1*9b6c1413SAndy Fiddaman# tzdb data for ships at sea and other miscellany 2*9b6c1413SAndy Fiddaman 345ba3153SMarcel Telka# This file is in the public domain, so clarified as of 445ba3153SMarcel Telka# 2009-05-17 by Arthur David Olson. 545ba3153SMarcel Telka 645ba3153SMarcel Telka# These entries are mostly present for historical reasons, so that 745ba3153SMarcel Telka# people in areas not otherwise covered by the tz files could "zic -l" 845ba3153SMarcel Telka# to a timezone that was right for their area. These days, the 945ba3153SMarcel Telka# tz files cover almost all the inhabited world, and the only practical 1045ba3153SMarcel Telka# need now for the entries that are not on UTC are for ships at sea 1145ba3153SMarcel Telka# that cannot use POSIX TZ settings. 1245ba3153SMarcel Telka 1345ba3153SMarcel Telka# Starting with POSIX 1003.1-2001, the entries below are all 1445ba3153SMarcel Telka# unnecessary as settings for the TZ environment variable. E.g., 1545ba3153SMarcel Telka# instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. 1645ba3153SMarcel Telka# 1745ba3153SMarcel Telka# Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours 1845ba3153SMarcel Telka# behind GMT but uses the completely misleading abbreviation "GMT". 1945ba3153SMarcel Telka 2045ba3153SMarcel TelkaZone Etc/GMT 0 - GMT 2145ba3153SMarcel TelkaZone Etc/UTC 0 - UTC 2245ba3153SMarcel Telka 2345ba3153SMarcel Telka# The following link uses older naming conventions, 2445ba3153SMarcel Telka# but it belongs here, not in the file 'backward', 2545ba3153SMarcel Telka# as functions like gmtime load the "GMT" file to handle leap seconds properly. 2645ba3153SMarcel Telka# We want this to work even on installations that omit the other older names. 2745ba3153SMarcel TelkaLink Etc/GMT GMT 2845ba3153SMarcel Telka 2945ba3153SMarcel TelkaLink Etc/UTC Etc/Universal 3045ba3153SMarcel TelkaLink Etc/UTC Etc/Zulu 3145ba3153SMarcel Telka 3245ba3153SMarcel TelkaLink Etc/GMT Etc/Greenwich 3345ba3153SMarcel TelkaLink Etc/GMT Etc/GMT-0 3445ba3153SMarcel TelkaLink Etc/GMT Etc/GMT+0 3545ba3153SMarcel TelkaLink Etc/GMT Etc/GMT0 3645ba3153SMarcel Telka 3745ba3153SMarcel Telka# Be consistent with POSIX TZ settings in the Zone names, 3845ba3153SMarcel Telka# even though this is the opposite of what many people expect. 3945ba3153SMarcel Telka# POSIX has positive signs west of Greenwich, but many people expect 4045ba3153SMarcel Telka# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 4145ba3153SMarcel Telka# the abbreviation "-04" and corresponds to 4 hours behind UT 4245ba3153SMarcel Telka# (i.e. west of Greenwich) even though many people would expect it to 4345ba3153SMarcel Telka# mean 4 hours ahead of UT (i.e. east of Greenwich). 4445ba3153SMarcel Telka 4545ba3153SMarcel Telka# Earlier incarnations of this package were not POSIX-compliant, 4645ba3153SMarcel Telka# and had lines such as 4745ba3153SMarcel Telka# Zone GMT-12 -12 - GMT-1200 4845ba3153SMarcel Telka# We did not want things to change quietly if someone accustomed to the old 4945ba3153SMarcel Telka# way does a 5045ba3153SMarcel Telka# zic -l GMT-12 5145ba3153SMarcel Telka# so we moved the names into the Etc subdirectory. 5245ba3153SMarcel Telka# Also, the time zone abbreviations are now compatible with %z. 5345ba3153SMarcel Telka 5445ba3153SMarcel TelkaZone Etc/GMT-14 14 - +14 5545ba3153SMarcel TelkaZone Etc/GMT-13 13 - +13 5645ba3153SMarcel TelkaZone Etc/GMT-12 12 - +12 5745ba3153SMarcel TelkaZone Etc/GMT-11 11 - +11 5845ba3153SMarcel TelkaZone Etc/GMT-10 10 - +10 5945ba3153SMarcel TelkaZone Etc/GMT-9 9 - +09 6045ba3153SMarcel TelkaZone Etc/GMT-8 8 - +08 6145ba3153SMarcel TelkaZone Etc/GMT-7 7 - +07 6245ba3153SMarcel TelkaZone Etc/GMT-6 6 - +06 6345ba3153SMarcel TelkaZone Etc/GMT-5 5 - +05 6445ba3153SMarcel TelkaZone Etc/GMT-4 4 - +04 6545ba3153SMarcel TelkaZone Etc/GMT-3 3 - +03 6645ba3153SMarcel TelkaZone Etc/GMT-2 2 - +02 6745ba3153SMarcel TelkaZone Etc/GMT-1 1 - +01 6845ba3153SMarcel TelkaZone Etc/GMT+1 -1 - -01 6945ba3153SMarcel TelkaZone Etc/GMT+2 -2 - -02 7045ba3153SMarcel TelkaZone Etc/GMT+3 -3 - -03 7145ba3153SMarcel TelkaZone Etc/GMT+4 -4 - -04 7245ba3153SMarcel TelkaZone Etc/GMT+5 -5 - -05 7345ba3153SMarcel TelkaZone Etc/GMT+6 -6 - -06 7445ba3153SMarcel TelkaZone Etc/GMT+7 -7 - -07 7545ba3153SMarcel TelkaZone Etc/GMT+8 -8 - -08 7645ba3153SMarcel TelkaZone Etc/GMT+9 -9 - -09 7745ba3153SMarcel TelkaZone Etc/GMT+10 -10 - -10 7845ba3153SMarcel TelkaZone Etc/GMT+11 -11 - -11 7945ba3153SMarcel TelkaZone Etc/GMT+12 -12 - -12 80
