620091Swollman# These entries are mostly present for historical reasons, so that
720091Swollman# people in areas not otherwise covered by the tz files could "zic -l"
8339631Sphilip# to a timezone that was right for their area.  These days, the
9149511Swollman# tz files cover almost all the inhabited world, and the only practical
10149511Swollman# need now for the entries that are not on UTC are for ships at sea
11149511Swollman# that cannot use POSIX TZ settings.

13307362Sbapt# Starting with POSIX 1003.1-2001, the entries below are all
14307362Sbapt# unnecessary as settings for the TZ environment variable.  E.g.,
15307362Sbapt# instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'.
16307362Sbapt#
17307362Sbapt# Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours
18307362Sbapt# behind GMT but uses the completely misleading abbreviation "GMT".

37307362Sbapt# Be consistent with POSIX TZ settings in the Zone names,

3975264Swollman# POSIX has positive signs west of Greenwich, but many people expect
4075264Swollman# positive signs east of Greenwich.  For example, TZ='Etc/GMT+4' uses
41307362Sbapt# the abbreviation "-04" and corresponds to 4 hours behind UT
4275264Swollman# (i.e. west of Greenwich) even though many people would expect it to
43257697Sedwin# mean 4 hours ahead of UT (i.e. east of Greenwich).
