The enclosed time zone abbreviation list update has been made possible with the help of the following people: Stephen J. Walick <steve@nshore.ncoast.org> pointed out the dateok.c function in C news. Geoff Collyer <geoff@world.std.com> and Henry Spencer of C News fame (Geoff authored the dateok.c function, along with Mark Moraes and Rich Walies via Rayan Zachariassen) Jon Postel <postel@venera.isi.org> sent me information compiled by Gary Dixon <GDixon@HIS-PHOENIX-MULTICS.ARPA>, Jim Falksen <Falksenj@HIS-PHOENIX-MULTICS.ARPA> and Gary M. Palter <Palter@HIS-PHOENIX-MULTICS.ARPA> of the Multics project, and John Colville of NSWIT, Australia. This compilation includes two references: Dobyns, Zipporah Pottenger, Ph.D. and MacGregor, Marcian B. "The Astrology Annual Reference Book." 1981. Michelsen, Neil F. "The American Ephemeris, 1971 to 1980." Nickolay Saukh <nms@jvd.msk.su> of JV Dialogue, Moscow, USSR supplied information about Moscow time zones. The anonymous authors of the BSD timezone() function I welcome corrections and additions. I would like to hear from any New Zealander who can clear up my confusion about NZDT -- is it GMT+1300 or GMT-1100? Is GMT+1300 even a legal offset? How does GMT+1300 affect date calculation? I also am uncertain about HST and HDT. One source says they are whole-hour zones; another, half-hour. Since the center of Hawaii is about 157 degrees West, I think that they are half-hour zones. However, a historical note I have found says the half-hour zones were abandoned in 1947. [Compiler's apology: please note that I don't endorse in any way the use of time zone abbreviations in mail headers. This list just acknowledges that the abbreviations are there.] Vic Abell <abe@mace.cc.purdue.edu> Tue May 28 14:35:38 EST 1991 Zone GMT + Description ACSST 10:30 Central Australian Summer ACST 9:30 Central Australian Standard ADT -3:00 Atlantic Daylight AESST 11:00 Eastern Australian Summer AEST 10:00 Eastern Australian Standard AHST -10:00 Alaska-Hawaii Standard AST -4:00 Atlantic Standard AT 2:00 Azores AWSST 8:00 Western Australian Summer AWST 7:00 Western Australian Standard BRA -3:00 Brazil BST 1:00 British Summer (also Brazil Standard) BST -3:00 Brazil Standard (also British Summer) BT 3:00 Baghdad (also Bering) BT -11:00 Bering (also Baghdad) CADT 10:30 Central Australian Daylight CAST 9:30 Central Australian Standard CAT -10:00 Central Alaskan CCT 8:00 China Coast CDT -5:00 Central Daylight CET 1:00 Central European CET DST 2:00 Central European Daylight CST -6:00 Central Standard DNT 1:00 Dansk Normal EAST 10:00 East Australian Standard EDT -4:00 Eastern Daylight EET 2:00 Eastern European EET DST 3:00 Eastern European Daylight EMT 1:00 Norway EST -5:00 Eastern Standard FST 2:00 French Summer FWT 1:00 French Winter GMT 0:00 Greenwich GST 10:00 Guam Standard (also Greenland Standard) GST -3:00 Greenland Standard (also Guam Standard) HDT -9:30 Hawaiian Daylight HFE 2:00 Heure Francais d'Ete HFH 1:00 Heure Francais d'Hiver HMT 3:00 Hellas HST -10:30 Hawaiian Standard IDLE 12:00 International Dateline, East IDLW -12:00 International Dateline, West IST 5:30 Indian Standard (also Israeli Standard) IST 2:00 Israeli Standard (also Indian Standard) IT 3:30 Iran ITA 1:00 Italy JST 9:00 Japanese Standard JT 7:30 Java KST 9:00 Korean Standard LIGT 10:00 Melbourne, Australia MAL 8:00 Malaysia MAT 3:00 Turkey MDT -6:00 Mountain Daylight MEST 2:00 Middle European Summer MET 1:00 Middle European MET DST 2:00 Middle European Daylight MEWT 1:00 Middle European Winter MEX -6:00 Mexico MEZ 1:00 Middle European MSD 3:00 Moscow Summer MSK 2:00 Moscow Winter MST -7:00 Mountain Standard MT 8:30 Moluccas NDT -2:30 Newfoundland Daylight NFT -3:30 Newfoundland NOR 1:00 Norway NST -3:30 Newfoundland Standard (also North Sumatran) NST 8:30 North Sumatran (also Newfoundland Standard) NT -11:00 Nome NZDT -11:00 New Zealand Daylight NZST 12:00 New Zealand NZT 12:00 New Zealand PDT -7:00 Pacific Daylight PST -8:00 Pacific Standard SADT 10:30 South Australian Daylight SAST 9:30 South Australian Standard SET 1:00 European -- Prague, Vienna SST 8:00 Singapore Standard (also Swedish Summer and South Sumatran) SST 7:00 South Sumatran (also Swedish Summer and Singapore Standard) SST 2:00 Swedish Summer (also South Sumatran and Singapore Standard) SWT 1:00 Swedish TST 3:00 Turkish Standard UT 0:00 Universal UTC 0:00 Universal Time Coordinated WADT 8:00 Western Australian Daylight WAST 7:00 Western Australian Standard WAT 1:00 West African WDT 9:00 Western Australian Daylight WET 0:00 Western European WET DST 1:00 Western European Daylight WST 8:00 Western Australian Standard WUT 1:00 Austria YDT -8:00 Yukon Daylight YST -9:00 Yukon Standard ZP4 -4:00 UTC + 4 hours ZP5 -5:00 UTC + 5 hours ZP6 -6:00 UTC + 6 hours
