by Paul Eggert May 25, 2015

May 25, 2015

It's March Madness time for daylight-saving rule changes. Here's a proposed change to the tz database to keep up with the latest political development, which affects time stamps starting March 29: * Latvia and Lithuania will not observe DST, starting this year.

Israel 2005-2007 -- Proposed Timezone Dates
by Ephraim Silverberg Dec. 13, 2004

Dec. 13, 2004

Attached are the diffs to 'asia' in tzdata2004e.tar.gz for the proposed dates for the State of Israel for the years 2005-2007. However, I don't know if they should be incorporated in the global database just yet as they have a long legislative path to pass before getting passed into law especially, as noted in the comments, since the Minister of Interior's own government objects to these dates. Nevertheless, I am sending this to the forum since these are better than no dates at all. Furthermore, even though there are no proposed dates for 2008 and beyond, I changed the default guesses to follow the proposed 2005-2007 rules. ___________________________________________________________________________ Ephraim Silverberg, CSE System Group, Phone number: 972-2-6585521 Hebrew University, Jerusalem, Israel.

Olso city
by Jesper Norgaard Welen Nov. 1, 2004

Nov. 1, 2004

There is a spelling mistake in the 'europe' file, where 'Olso' should be 'Oslo' (the capital of Norway). Maybe because Arthur David Olson was also mentioned in the file!?

FW: Time Zone change in GEORGIA (Eastern Europe), time zone is no w GMT+3 (no longer GMT+4)
by Olson, Arthur David (NIH/NCI) Oct. 29, 2004

Oct. 29, 2004

Aiet Kolkhi is not on the time zone mailing list; direct replies appropriately. The change of Georgia to GMT+3 is already reflected in tzdata2004e.tar.gz; the suggested move of Georgia to Europe from Asia is not. --ado -----Original Message----- From: Aiet Kolkhi [mailto:aiet@qartuli.net] Sent: Sunday, October 24, 2004 4:39 PM To: tz(a)lecserver.nci.nih.gov Subject: Time Zone change in GEORGIA (Eastern Europe), time zone is now GMT+3 (no longer GMT+4) Hello, There has been a time zone change in GEORGIA (capital: Tbilisi). Georgia used to be a GMT+4 country, with DST rules just like Berlin or Paris, but since June 27, 2004, the newly-elected Parliament chose to set national time GEST one hour erlier, just like it was in the old days. As a result, the timzone Georgia belongs is GMT+3 (+1 hour during Daylight Saiving Times, just like it is now). DST rules remain, i.e. DST starts on March 28 and ends on Oct. 31. You may read BBC story about the change here: http://news.bbc.co.uk/1/hi/world/europe/3843511.stm Also, the information has been already corrected at timeanddate.com Here is the link to Tbilisi, Georgia: http://www.timeanddate.com/worldclock/city.html?n=371 Another important notice: It would be more proper and politically correct to list Georgia in (East) Europe section and not in Asia. Georgia was considered Asian country due to improper information during Soviet times, but since the break-up of the Soviet, Georgia tends to be included in Europe rather than in Asia in more and more places. The BBC link I provided above for example also includes Georgia in Europian region. It is correct, since Georgia has always been more Europian country than Asian, with Christian religion since 4th AD and Europian traditions. Georgia is also a member of Europian Council and the EU flag is hanging next to the Georgian flag in front of Georgian Parliament :) Please CC any inquiries/replies regarding this matter DIRECTLY to my address, as I'm not subscribed to this list. Thank you. -- Best regards, Aiet Kolkhi mailto:aiet@qartuli.net http://aiet.qartuli.net

Cuba on DST until 2005
by Steffen Thorsen Oct. 29, 2004

Oct. 29, 2004

Not to interrupt your discussion about Georgia, but... Evert van der Veer <evert.van.der.veer(a)wanadoo.nl> informed me that Cuba was not going back to standard time this year. I was able to find a news arcticle about it, quoted: > To conserve energy, Cuban authorities are closing 110 businesses, > shortening the workday and school day by a half hour, extending > daylight-saving time until October 2005 and shifting production > schedules. The original (subscription) is in the Dallas Morning News from 2004-10-14: http://www.dallasnews.com/sharedcontent/dws/news/world/cuba/stories/101504d… A number of other newspapers carry the same article without subscription, including http://www.kansas.com/mld/kansas/news/world/9920684.htm regards, Steffen

Using tz as linked libraries
by Wendel Schultz Oct. 22, 2004

Oct. 22, 2004

Has anybody had any success linking to the libraries and using these functions? Any sample programs that illustrate this? Also, is it better to build this under Cygwin or use MS VC++ to compile?

difftime
by Olson, Arthur David (NIH/NCI) Oct. 21, 2004

So...can we apply our hard-earned knowledge of modular arithmetic to the task of getting difftime to do the right thing in the face of the various types that time_t is allowed to assume?
