From e77ed9159b8c5a93a2a01fd3d227966302e54dac Mon Sep 17 00:00:00 2001 From: apb Date: Thu, 26 Dec 2013 16:40:53 +0000 Subject: [PATCH] Import tzdata2013i from ftp://ftp.iana.org/tz/releases/tzdata2013i.tar.gz. Major changes from tzdata2013d to tzdata2013e: Fiji (Pacific/Fiji) DST in 2013 starts on October 27, not October 20. Several zones have been turned into links, either to correct errors, or where the differences were in older data (before 1943) that was thought to be unreliable. Some time zone abbreviations have been changed. Major changes from tzdata2013e to tzdata2013f: Tocantins, Brazil (America/Araguaina) DST will not start in September 2013. Jordan (Asia/Amman) moves to permanent UTC+3 (instead of UTC+2 with permanent DST since 2012). Palestine (Asia/Hebron and Asia/Gaza) will end DST at 00:00, not 01:00, as from September 2013. Major changes from tzdata2013f to tzdata2013g: Morocco (Africa/Casablanca) now observes DST from the last Sunday in March to the last Sunday in October, not April to September. respectively. Major changes from tzdata2013g to tzdata2013h: Libya (Africa/Tripoli) has switched its time zone back to UTC+2 without DST, instead of UTC+1 with DST. Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules. Acre, Brazil (America/Rio_Branco) and (we guess) western Amazonas, Brazil (America/Eirunepe), will switch from UTC-4 to UTC-5 on 2013-11-10. Add entries for DST transitions in Morocco in the year 2038. This avoids some year-2038 glitches introduced in 2013g. Major changes from tzdata2013h to tzdata2013i: Jordan (Asia/Amman) switches back to UTC+2 standard time at 00:00 on December 20, 2013. The 2006-2011 DST transition schedule is planned to resume in 2014. The switch to permanent UTC+3 is cancelled. In 2004, Cuba (America/Havana) began DST on March 28, not April 4. The files solar87, solar88, and solar89 are no longer distributed. The zones built from those files (Asia/Riyadh{87,88,89}) and Mideast/Riyadh{87,88,89}) are no longer installed. They were a negative experiment -- that is, a demonstration that tz data can represent solar time only with some difficulty and error. Their presence in the distribution caused confusion, as Riyadh civil time was generally not solar time in those years. --- share/zoneinfo/Makefile | 210 ++++++++++++++++------------ share/zoneinfo/README | 64 +++++++++ share/zoneinfo/africa | 95 +++++++++---- share/zoneinfo/antarctica | 27 ++-- share/zoneinfo/asia | 101 ++++++++++---- share/zoneinfo/australasia | 31 ++++- share/zoneinfo/backward | 14 +- share/zoneinfo/etcetera | 4 +- share/zoneinfo/europe | 126 ++++++++++++----- share/zoneinfo/iso3166.tab | 6 +- share/zoneinfo/leap-seconds.list | 231 +++++++++++++++++++++++++++++++ share/zoneinfo/leapseconds | 70 ++-------- share/zoneinfo/leapseconds.awk | 66 +++++++++ share/zoneinfo/northamerica | 150 ++++++++------------ share/zoneinfo/southamerica | 72 ++++++++-- share/zoneinfo/zone.tab | 32 ++--- 16 files changed, 903 insertions(+), 396 deletions(-) create mode 100644 share/zoneinfo/README create mode 100644 share/zoneinfo/leap-seconds.list create mode 100644 share/zoneinfo/leapseconds.awk diff --git a/share/zoneinfo/Makefile b/share/zoneinfo/Makefile index 365937863f44..3c4523d86f5c 100644 --- a/share/zoneinfo/Makefile +++ b/share/zoneinfo/Makefile @@ -6,7 +6,7 @@ PACKAGE= tzcode # Version numbers of the code and data distributions. -VERSION= 2013d +VERSION= 2013i # Email address for bug reports.

The insertion of leap seconds into UTC is currently the +# responsibility of the International Earth Rotation Service, +# which is located at the Paris Observatory: +# +# Central Bureau of IERS +# 61, Avenue de l'Observatoire +# 75014 Paris, France. +# +# Leap seconds are announced by the IERS in its Bulletin C +# +# See hpiers.obspm.fr or www.iers.org for more details. +# +# All national laboratories and timing centers use the +# data from the BIPM and the IERS to construct their +# local realizations of UTC. +# +# Although the definition also includes the possibility +# of dropping seconds ("negative" leap seconds), this has +# never been done and is unlikely to be necessary in the +# foreseeable future. +# +# 5. If your system keeps time as the number of seconds since +# some epoch (e.g., NTP timestamps), then the algorithm for +# assigning a UTC time stamp to an event that happens during a positive +# leap second is not well defined. The official name of that leap +# second is 23:59:60, but there is no way of representing that time +# in these systems. +# Many systems of this type effectively stop the system clock for +# one second during the leap second and use a time that is equivalent +# to 23:59:59 UTC twice. For these systems, the corresponding TAI +# timestamp would be obtained by advancing to the next entry in the +# following table when the time equivalent to 23:59:59 UTC +# is used for the second time. Thus the leap second which +# occurred on 30 June 1972 at 23:59:59 UTC would have TAI +# timestamps computed as follows: +# +# ... +# 30 June 1972 23:59:59 (2287785599, first time): TAI= UTC + 10 seconds +# 30 June 1972 23:59:60 (2287785599,second time): TAI= UTC + 11 seconds +# 1 July 1972 00:00:00 (2287785600) TAI= UTC + 11 seconds +# ... +# +# If your system realizes the leap second by repeating 00:00:00 UTC twice +# (this is possible but not usual), then the advance to the next entry +# in the table must occur the second time that a time equivlent to +# 00:00:00 UTC is used. Thus, using the same example as above: +# +# ... +# 30 June 1972 23:59:59 (2287785599): TAI= UTC + 10 seconds +# 30 June 1972 23:59:60 (2287785600, first time): TAI= UTC + 10 seconds +# 1 July 1972 00:00:00 (2287785600,second time): TAI= UTC + 11 seconds +# ... +# +# in both cases the use of timestamps based on TAI produces a smooth +# time scale with no discontinuity in the time interval. +# +# This complexity would not be needed for negative leap seconds (if they +# are ever used).
