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?

dead code in zic
by christos＠zoulas.com March 7, 2013

March 7, 2013

On LP32 machines, the following code is dead: dayoff is long min_time is zic_t -> int_fast64_t if (dayoff < min_time / SECSPERDAY) { error(_("time too small")); return; } if (dayoff > max_time / SECSPERDAY) { error(_("time too large")); return; } The vax gcc-4.1 detects this; later versions of gcc don't. But all of them will warn, if you change min_time and max_time from const zic_t to #define's. What's the correct fix here? http://releng.netbsd.org/builds/HEAD/201303041020Z/vax.build.failed christos

by Carlos Raúl Perasso March 6, 2013

March 6, 2013

The Paraguayan Electric Company (ANDE) plans to move out of DST a couple of weeks earlier this year. There is nothing final yet. An article from a local newspaper: http://www.abc.com.py/nacionales/ande-quiere-adelantar-el-atraso-de-los-rel… I'll will report changes on this subject. Carlos Perasso

Has that been considered before? See http://www.ietf.org/timezones/code/Theory In my opinion there will be a loss of flexibility if the information is published as a RFC. Regards, -sm
