# 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.

# The following link uses older naming conventions,

# We use POSIX-style signs in the Zone names and the output abbreviations,
# 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 "GMT+4" and corresponds to 4 hours behind UTC
# (i.e. west of Greenwich) even though many people would expect it to
# mean 4 hours ahead of UTC (i.e. east of Greenwich).
#
# In the draft 5 of POSIX 1003.1-200x, the angle bracket notation
# (which is not yet supported by the tz code) allows for
# TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to
# ISO 8601 you can use TZ='<-0400>+4'.  Thus the commonly-expected
# offset is kept within the angle bracket (and is used for display)
# while the POSIX sign is kept outside the angle bracket (and is used
# for calculation).
#
# Do not use a TZ setting like TZ='GMT+4', which is four hours behind
# GMT but uses the completely misleading abbreviation "GMT".

# 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.
