From b7680b6762d82401512d0859ba42fd080233adcc Mon Sep 17 00:00:00 2001 From: Edwin Groothuis Date: Fri, 6 Mar 2015 21:41:35 +0000 Subject: Vendor import of tzdata2015a: hanges affecting future time stamps The Mexican state of Quintana Roo, represented by America/Cancun, will shift from Central Time with DST to Eastern Time without DST on 2015-02-01 at 02:00. (Thanks to Steffen Thorsen and Gwillim Law.) Chile will not change clocks in April or thereafter; its new standard time will be its old daylight saving time. This affects America/Santiago, Pacific/Easter, and Antarctica/Palmer. (Thanks to Juan Correa.) New leap second 2015-06-30 23:59:60 UTC as per IERS Bulletin C 49. (Thanks to Tim Parenti.) Changes affecting past time stamps Iceland observed DST in 1919 and 1921, and its 1939 fallback transition was Oct. 29, not Nov. 29. Remove incorrect data from Shanks about time in Iceland between 1837 and 1908. Some more zones have been turned into links, when they differed from existing zones only for older time stamps. As usual, these changes affect UTC offsets in pre-1970 time stamps only. Their old contents have been moved to the 'backzone' file. The affected zones are: Asia/Aden, Asia/Bahrain, Asia/Kuwait, and Asia/Muscat. --- antarctica | 9 +++++---- asia | 28 ++++++++-------------------- backward | 2 +- europe | 29 +++++++++++++---------------- leap-seconds.list | 24 +++++++++++++++++------- northamerica | 27 +++++++++++++++++++++++---- southamerica | 17 ++++++++++++----- zone.tab | 2 +- zone1970.tab | 2 +- 9 files changed, 81 insertions(+), 59 deletions(-) diff --git a/antarctica b/antarctica index 1deff8e4ed09..ebae9940717c 100644 --- a/antarctica +++ b/antarctica @@ -47,8 +47,8 @@ Rule ChileAQ 2009 only - Mar Sun>=9 3:00u 0 - Rule ChileAQ 2010 only - Apr Sun>=1 3:00u 0 - Rule ChileAQ 2011 only - May Sun>=2 3:00u 0 - Rule ChileAQ 2011 only - Aug Sun>=16 4:00u 1:00 S -Rule ChileAQ 2012 max - Apr Sun>=23 3:00u 0 - -Rule ChileAQ 2012 max - Sep Sun>=2 4:00u 1:00 S +Rule ChileAQ 2012 2015 - Apr Sun>=23 3:00u 0 - +Rule ChileAQ 2012 2014 - Sep Sun>=2 4:00u 1:00 S # Argentina - year-round bases # Belgrano II, Confin Coast, -770227-0343737, since 1972-02-05 @@ -354,9 +354,10 @@ Zone Antarctica/Rothera 0 - zzz 1976 Dec 1 # # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Antarctica/Palmer 0 - zzz 1965 - -4:00 ArgAQ AR%sT 1969 Oct 5 + -4:00 ArgAQ AR%sT 1969 Oct 5 -3:00 ArgAQ AR%sT 1982 May - -4:00 ChileAQ CL%sT + -4:00 ChileAQ CL%sT 2015 Apr 26 3:00u + -3:00 - CLT # # # McMurdo Station, Ross Island, since 1955-12 diff --git a/asia b/asia index 1a2bd12ad2a2..8f33b162097d 100644 --- a/asia +++ b/asia @@ -145,10 +145,7 @@ Zone Asia/Baku 3:19:24 - LMT 1924 May 2 4:00 Azer AZ%sT # Bahrain -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Asia/Bahrain 3:22:20 - LMT 1920 # Manamah - 4:00 - GST 1972 Jun - 3:00 - AST +# See Asia/Qatar. # Bangladesh # From Alexander Krivenyshev (2009-05-13): @@ -1731,9 +1728,7 @@ Zone Asia/Pyongyang 8:23:00 - LMT 1908 Apr 1 ############################################################################### # Kuwait -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Asia/Kuwait 3:11:56 - LMT 1950 - 3:00 - AST +# See Asia/Riyadh. # Laos # See Asia/Bangkok. @@ -1954,12 +1949,7 @@ Zone Asia/Kathmandu 5:41:16 - LMT 1920 5:45 - NPT # Nepal Time # Oman - -# Milne says 3:54:24 was the meridian of the Muscat Tidal Observatory. - -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Asia/Muscat 3:54:24 - LMT 1920 - 4:00 - GST +# See Asia/Dubai. # Pakistan @@ -2453,6 +2443,7 @@ Zone Asia/Manila -15:56:00 - LMT 1844 Dec 31 Zone Asia/Qatar 3:26:08 - LMT 1920 # Al Dawhah / Doha 4:00 - GST 1972 Jun 3:00 - AST +Link Asia/Qatar Asia/Bahrain # Saudi Arabia # @@ -2479,6 +2470,8 @@ Zone Asia/Qatar 3:26:08 - LMT 1920 # Al Dawhah / Doha # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Riyadh 3:06:52 - LMT 1947 Mar 14 3:00 - AST +Link Asia/Riyadh Asia/Aden # Yemen +Link Asia/Riyadh Asia/Kuwait # Singapore # taken from Mok Ly Yng (2003-10-30) @@ -2767,6 +2760,7 @@ Zone Asia/Ashgabat 3:53:32 - LMT 1924 May 2 # or Ashkhabad # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Dubai 3:41:12 - LMT 1920 4:00 - GST +Link Asia/Dubai Asia/Muscat # Oman # Uzbekistan # Byalokoz 1919 says Uzbekistan was 4:27:53. @@ -2851,10 +2845,4 @@ Zone Asia/Ho_Chi_Minh 7:06:40 - LMT 1906 Jul 1 7:00 - ICT # Yemen - -# Milne says 2:59:54 was the meridian of the saluting battery at Aden, -# and that Yemen was at 1:55:56, the meridian of the Hagia Sophia. - -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Asia/Aden 2:59:54 - LMT 1950 - 3:00 - AST +# See Asia/Riyadh. diff --git a/backward b/backward index 00cbfc416426..3ceda884bdcf 100644 --- a/backward +++ b/backward @@ -5,7 +5,7 @@ # and their old names.
