# This file is in the public domain, so clarified as of
# 2009-05-17 by Arthur David Olson.

# These entries are mostly present for historical reasons, so that
# people in areas not otherwise covered by the tz files could "zic -l"
# to a time zone that was right for their area.  These days, the
# tz files cover almost all the inhabited world, and the only practical
# need now for the entries that are not on UTC are for ships at sea
# that cannot use POSIX TZ settings.

# 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
Zone	Etc/UCT		0	-	UCT

# The following link uses older naming conventions,
# but it belongs here, not in the file 'backward',
# as functions like gmtime load the "GMT" file to handle leap seconds properly.
# We want this to work even on installations that omit the other older names.
Link	Etc/GMT				GMT

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.
