# tzdb data for ships at sea and other miscellany
# This file is in the public domain, so clarified as of
# 2009-05-17 by Arthur David Olson.
# These entries are for uses not otherwise covered by the tz database.
# Their main practical use is for platforms like Android that lack
# support for POSIX-style TZ strings. 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".
Zone Etc/GMT 0 - GMT
Zone Etc/UTC 0 - UTC
# The following link uses older naming conventions,
# but it belongs here, not in the file 'backward',
# as functions like gmtime load the "UTC" file to handle leap seconds properly.
# We want this to work even on installations that omit the other older names.
Link Etc/UTC UTC
Link Etc/UTC Etc/Universal
Link Etc/UTC Etc/Zulu
Link Etc/GMT Etc/Greenwich
Link Etc/GMT Etc/GMT-0
Link Etc/GMT Etc/GMT+0
Link Etc/GMT Etc/GMT0
# 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.
