Paraguay DST ends earlier
by Steffen Thorsen March 15, 2013

March 15, 2013

A user tipped us that Paraguay will end DST on 2013-03-24 00:00. We've been able to find a government source that confirms this, along with news from media, but the final decree might not be out yet. They do not tell if this will be a permanent change or just this year. Government source (Spanish): http://www.ande.gov.py/interna.php?id=1075 Translated by Google: "The president of the Directors National of Electricity (ANDE), Carlos Heisele, announced the change of schedule for the next 24 March, with which the clocks of the country should fall behind 60 minutes . This action is performed normally in the second week of the month of April, however forward the change of schedule by request of the citizens." We will keep this page updated: (Permanent link, English) http://www.timeanddate.com/news/time/paraguay-dst-march-2013.html Best regards, Steffen Thorsen - timeanddate.com

Haiti on DST
by Steffen Thorsen March 14, 2013

March 14, 2013

It appears that Haiti is observing DST this year as well, same rules as US/Canada. They did it last year as well, and it looks like they are going to observe DST every year now (based on the sources listed below). A user tipped us, we found these sources that verifies it: http://radiovision2000haiti.net/public/haiti-avis-changement-dheure-dimanch… http://www.canalplushaiti.net/?p=6714 Best regards, Steffen Thorsen - timeanddate.com

windows [MSVC] port progress
by random832＠fastmail.us March 13, 2013

March 13, 2013

I've made a makefile that can build the library functions (64-bit time_t only, and haven't done anything yet about MSVCRT functions showing up through names that tzcode doesn't define such as localtime_s or _ftime [or the 32-bit names]), and successfully compiled zdump. I was wondering if anyone had any ideas which approach would be best for implementing the 32-bit functions. Some background: MSVC defines two sets of time functions: for 32-bit and 64-bit time_t. But some functions (e.g. tzset and strftime) are shared between them. (VC2003 defines the default names as 32-bit, and I don't know if VC6 has the 64-bit functions at all - making it work on these versions may be somewhat more difficult) I could: A. Compile separate 32 and 64 bit versions of the library (what happens if a single program tries to call both?) B. Compile a single library with 32 and 64 bit versions of functions, a custom tzset function that calls both (this will pull in most of the 64-bit library when compiling a 32-bit program, but I can avoid pulling in the 32-bit objects when compiling a 64-bit program) C. Write wrapper 32-bit functions for 64-bit functions - a bit less bloated than solution B, but more work. D. ??? I want to eventually customize tzset anyway, to get the local time zone from the system settings when TZ is not set (CLDR contains a mapping from Windows time zone names to tzdata ones). Speaking of which, does anyone on the list have a non-English version of Windows to test something with?

So, the island of Hispaniola is divided in its DST observance. The Dominican Republic does not observe DST. Before this change, crossing the Haiti/DR border meant a transition between UTC-4 and UTC-5 all year long. Now, during DST, they are both UTC-4. Regards, Steve Jones OnTimeZone.com

Ukraine Time Change
by Wong Ren March 10, 2013

March 10, 2013

Alexander Krivenyshev had written: "The Ministry of Economic Development and Trade of Ukraine has submitted a bill to abolish the daylight saving time. If approved, new bill will go into effect on March 1, 2013 and Ukraine will use UTC+2 year around" Does anyone know what will be new time zone abbreviation since Ukraine used to have EET ? Also, the tz2013a does not have the Ukraine time change, was the bill approved and any update soon?

Cuba DST start as US/Canada
by Steffen Thorsen March 9, 2013

March 9, 2013

FYI: Granma, the official organ of the government confirms a 2013-03-10 DST start this year. The database already assumes this, so no change is necessary, but Cuba has had different rules the past two years, so it was not obvious that this would be the start date this year. http://www.granma.cubaweb.cu/2013/03/04/nacional/artic10.html Best regards, Steffen Thorsen - timeanddate.com

Well, yes, but it's just dumping the MSVC implementation of timezones, which is less useful than if I could get it to link against the tzcode library. I did have to switch from environ-manipulation to putenv (need to make it do that conditionally then I'll make a patch) and call tzset. How exactly was it working before without ever calling tzset? Am I missing something? Or is it just that most unix implementations, and the tzcode implementation, happen to be tolerant of calling localtime without calling tzset?

Timezones Morocco 2013 incorrect
by Erik Homoet March 7, 2013

March 7, 2013

Hi, For our internet airline booking engine of flights we¹re using the tzdata2012j version. In this version the DST timing for Morroco is not correct. We¹re facing a lot of problems because of this, this because a large amount of flights are departing from Morocco between 23:00 and 24:00. Morocco is also on Wintertime during the month of Ramadan. The correct timezone should be: WET DST starts on Sunday, 28 April 2013, 02:00 local standard time. DST ends on Tuesday, 9 July 2013, 03:00 local daylight time. DST starts on Thursday, 8 August 2013, 02:00 local standard time. DST ends on Sunday, 29 September 2013, 03:00 local daylight time. Source: http://www.timeanddate.com/worldclock/city.html?n=60 Would you please be so kind to give me an indication when this can be changed?
