# 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 mostly present for historical reasons, so that
|
|
# people in areas not otherwise covered by the tz files could "zic -l"
|
|
# to a timezone 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/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.

# 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.
