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. 122744Swollman 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". 19307362Sbapt 202744SwollmanZone Etc/GMT 0 - GMT 2120091SwollmanZone Etc/UTC 0 - UTC 2220091Swollman 2343009Swollman# The following link uses older naming conventions, 24270817Spluknet# but it belongs here, not in the file 'backward', 25199405Sobrien# as functions like gmtime load the "UTC" file to handle leap seconds properly. 2643009Swollman# We want this to work even on installations that omit the other older names. 27199405SobrienLink Etc/UTC UTC 2843009Swollman 2920091SwollmanLink Etc/UTC Etc/Universal 3020091SwollmanLink Etc/UTC Etc/Zulu 3120091Swollman 322744SwollmanLink Etc/GMT Etc/Greenwich 332744SwollmanLink Etc/GMT Etc/GMT-0 342744SwollmanLink Etc/GMT Etc/GMT+0 352744SwollmanLink Etc/GMT Etc/GMT0 362744Swollman 37307362Sbapt# Be consistent with POSIX TZ settings in the Zone names, 3875264Swollman# even though this is the opposite of what many people expect. 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). 442744Swollman 452744Swollman# Earlier incarnations of this package were not POSIX-compliant, 462744Swollman# and had lines such as 472744Swollman# Zone GMT-12 -12 - GMT-1200 482744Swollman# We did not want things to change quietly if someone accustomed to the old 492744Swollman# way does a 502744Swollman# zic -l GMT-12 512744Swollman# so we moved the names into the Etc subdirectory. 52307362Sbapt# Also, the time zone abbreviations are now compatible with %z. 532744Swollman 54307362SbaptZone Etc/GMT-14 14 - +14 55307362SbaptZone Etc/GMT-13 13 - +13 56307362SbaptZone Etc/GMT-12 12 - +12 57307362SbaptZone Etc/GMT-11 11 - +11 58307362SbaptZone Etc/GMT-10 10 - +10 59307362SbaptZone Etc/GMT-9 9 - +09 60307362SbaptZone Etc/GMT-8 8 - +08 61307362SbaptZone Etc/GMT-7 7 - +07 62307362SbaptZone Etc/GMT-6 6 - +06 63307362SbaptZone Etc/GMT-5 5 - +05 64307362SbaptZone Etc/GMT-4 4 - +04 65307362SbaptZone Etc/GMT-3 3 - +03 66307362SbaptZone Etc/GMT-2 2 - +02 67307362SbaptZone Etc/GMT-1 1 - +01 68307362SbaptZone Etc/GMT+1 -1 - -01 69307362SbaptZone Etc/GMT+2 -2 - -02 70307362SbaptZone Etc/GMT+3 -3 - -03 71307362SbaptZone Etc/GMT+4 -4 - -04 72307362SbaptZone Etc/GMT+5 -5 - -05 73307362SbaptZone Etc/GMT+6 -6 - -06 74307362SbaptZone Etc/GMT+7 -7 - -07 75307362SbaptZone Etc/GMT+8 -8 - -08 76307362SbaptZone Etc/GMT+9 -9 - -09 77307362SbaptZone Etc/GMT+10 -10 - -10 78307362SbaptZone Etc/GMT+11 -11 - -11 79307362SbaptZone Etc/GMT+12 -12 - -12 80
