27# We use POSIX-style signedness in the names and output, 28# internal-style signedness in the specifications. 29# For example, TZ=Etc/GMT+4 corresponds to 4 hours _behind_ UTC; 30# it is equivalent to TZ=GMT+4, which is implemented directly as per POSIX.
| 27# We use POSIX-style signs in the Zone names and the output abbreviations, 28# even though this is the opposite of what many people expect. 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). 34# 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). 42# 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".
