Since this change is now nearly 48 hours in the past, I have attached a proposed diff for the new Libya rules (reproduced below). The specific decisions I've made are, of course, debatable, but I think they're rather consistent with past practice. - Since Libya was previously on UTC+2 year-round, treat the change of 2012-11-10 to be a zone change to UTC+1. - Since Libya plan to observe DST changes roughly in sync with Europe (either two days before them or five days after them, so as to fall on lastFri instead of lastSun), we can favor CE(S)T, used by neighboring Tunisia, over other nearby designations for UTC+1 (like WAT). This is also more consistent with previous designations. diff --git a/africa b/africa index bbec05e..7544899 100644 --- a/africa +++ b/africa @@ -423,7 +423,34 @@ Zone Africa/Monrovia -0:43:08 - LMT 1882 ############################################################################### # Libya - +# From Even Scharning (2012-11-10): +# Libya set their time one hour back at 02:00 on Saturday November 10. +# http://www.libyaherald.com/2012/11/04/clocks-to-go-back-an-hour-on-saturday/ +# Here is an official source [in Arabic]: http://ls.ly/fb6Yc +# +# From Steffen Thorsen (2012-11-10): +# We have gotten the text in the resolution translated to English...: +# ... +# Point (2) +# For the year 2012, the timing delay will be one hour at (2:00) am on +# Saturday 10/Nov./2012 so it becomes (1:00) am. +# Point (3) +# For the comings new years, the start of summer timing will be considered at +# (1:00) am from the last Friday in March of each year by shifting forward one +# hour so that the time will be (2:00) am. +# Point (4) +# For the comings new years, the end of summer timing will be considered at +# (2:00) am from the last Friday in October of each year by delaying one hour +# so that the time will be (1:00) am. +# ... +# +# From Tim Parenti (2012-11-11): +# Treat the 2012-11-10 change as a zone change from UTC+2 to UTC+1. +# The DST rules planned for 2013 and onward roughly mirror those of Europe +# (either two days before them or five days after them, so as to fall on +# lastFri instead of lastSun).

Sorry about the double post. (The list was slow, so I thought my message was caught by a spam filter.)

Here is an official source: http://ls.ly/fb6Yc

Some people reporting this change to us had some doubt if it actually would be adopted, but probably it will.

We have gotten the text in the resolution translated to English (given it was an image and not so easy to automatically translate), and it is like this:

After reviewing the Constitutional Declaration and modify it. - depending upon law No. 5 of year 2012 about the official holidays. - And upon the decision of the National Transitional Council No. 184 , year 2011 on the accreditation of the transitional government. - And upon the decision by the Council of Ministers at its regular Forty-one meeting for the year 2012 "they decided"

Point(1) The action of summer timing must be dependable as set in this resolution. Point (2) For the year 2012 , the timing delay will be one hour at (2:00) am on Saturday 10 /Nov./2012 so it becomes (1:00) am. Point (3) For the comings new years, the start of summer timing will be considered at (1:00) am from the last Friday in March of each year by shifting forward one hour so that the time will be ( 2:00) am. Point (4) For the comings new years, the end of summer timing will be considered at (2:00) am from the last Friday in October of each year by delaying one hour so that the time will be (1:00) am. Point (5) The number of official working hours remain the same. Point (6) Resolution terms must be applied since its release date, all others infringe decision must be neglected, authorities must implement and published it in the Official Newspaper.
