These days, the 91315084cSEdwin Groothuis# tz files cover almost all the inhabited world, and the only practical 101315084cSEdwin Groothuis# need now for the entries that are not on UTC are for ships at sea 111315084cSEdwin Groothuis# that cannot use POSIX TZ settings. 121315084cSEdwin Groothuis 138fdf5721SBaptiste Daroussin# Starting with POSIX 1003.1-2001, the entries below are all 148fdf5721SBaptiste Daroussin# unnecessary as settings for the TZ environment variable. E.g., 158fdf5721SBaptiste Daroussin# instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. 168fdf5721SBaptiste Daroussin# 178fdf5721SBaptiste Daroussin# Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours 188fdf5721SBaptiste Daroussin# behind GMT but uses the completely misleading abbreviation "GMT". 198fdf5721SBaptiste Daroussin 201315084cSEdwin GroothuisZone Etc/GMT 0 - GMT 211315084cSEdwin GroothuisZone Etc/UTC 0 - UTC 221315084cSEdwin GroothuisZone Etc/UCT 0 - UCT 231315084cSEdwin Groothuis 241315084cSEdwin Groothuis# The following link uses older naming conventions, 25eb1c1a05SSergey Kandaurov# but it belongs here, not in the file 'backward', 262289da42SEdwin Groothuis# as functions like gmtime load the "UTC" file to handle leap seconds properly. 271315084cSEdwin Groothuis# We want this to work even on installations that omit the other older names. 282289da42SEdwin GroothuisLink Etc/UTC UTC 291315084cSEdwin Groothuis 301315084cSEdwin GroothuisLink Etc/UTC Etc/Universal 311315084cSEdwin GroothuisLink Etc/UTC Etc/Zulu 321315084cSEdwin Groothuis 331315084cSEdwin GroothuisLink Etc/GMT Etc/Greenwich 341315084cSEdwin GroothuisLink Etc/GMT Etc/GMT-0 351315084cSEdwin GroothuisLink Etc/GMT Etc/GMT+0 361315084cSEdwin GroothuisLink Etc/GMT Etc/GMT0 371315084cSEdwin Groothuis 388fdf5721SBaptiste Daroussin# Be consistent with POSIX TZ settings in the Zone names, 391315084cSEdwin Groothuis# even though this is the opposite of what many people expect. 401315084cSEdwin Groothuis# POSIX has positive signs west of Greenwich, but many people expect 411315084cSEdwin Groothuis# positive signs east of Greenwich.
