29# POSIX has positive signs west of Greenwich, but many people expect
30# positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses
31# the abbreviation "GMT+4" and corresponds to 4 hours behind UTC
32# (i.e. west of Greenwich) even though many people would expect it to
33# mean 4 hours ahead of UTC (i.e. east of Greenwich).

35# In the draft 5 of POSIX 1003.1-200x, the angle bracket notation
36# (which is not yet supported by the tz code) allows for
37# TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to
38# ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected
39# offset is kept within the angle bracket (and is used for display)
40# while the POSIX sign is kept outside the angle bracket (and is used
41# for calculation).

43# Do not use a TZ setting like TZ='GMT+4', which is four hours behind
44# GMT but uses the completely misleading abbreviation "GMT".
