2440ca2003-03-30Mirar (Pontus Hagland) # 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
93f75a2013-11-21Henrik Grubbström (Grubba) # the abbreviation "GMT+4" and corresponds to 4 hours behind UT

2440ca2003-03-30Mirar (Pontus Hagland) # 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".
