# 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,

|
|
# way does a
|
|
# zic -l GMT-12
|
|
# so we moved the names into the Etc subdirectory.
