Re: Kazakhstan question
by Gwillim Law Sept. 16, 2006

I've gone into the archives of the tz mailing list to gather what information there is on this question. A flurry of messages went out on the tz mailing list in May and June, 2005 on the subject of Kazakhstan's time zones, when the country announced the end of DST. In 1996, according to a technical publication of the International Air Transport Association, Kazakhstan split into three time zones. Before that time, it had been all UTC+6 with DST. Afterward, Aktau, Atyrau, and Uralsk oblasts (aka Mangghystau, Atyrau, and West Kazakhstan) went to UTC+4, and Aktyubinsk (aka Aqtöbe) went to UTC+5. In 2005, according to a correspondent in Kazakhstan, those four oblasts united on UTC+5, as the entire country was dropping its observance of DST. So I think the answer is that Atyrau was in Asia/Aqtau from 1996 to 2005. (I tried to send this message two days ago, but it didn't get through.) -- Gwillim Law ----- Original Message ----- From: "Jesper Norgaard Welen" <jnorgard(a)prodigy.net.mx> > # The zone closer to UTC is the former Western zone (probably still called > the > # same), encompassing four provinces in the west: Aqtobe, Atyrau, > # Mangghystau, and West Kazakhstan.

Thank, you Robert! It never occurred to me that eve and evening could be something different - and perhaps I have also the handicap that Christmas Eve in Denmark is where all the fun stuff happens, exchanging gifts, dancing around the Christmas tree etc. and there is nothing special about Christmas Day (the day after, as I understand it). While in the US the presents are received on Christmas Day. I think also that it would be strange to start a new period like Ramadan having the first day different than the rest. But if we can get a clearer web link or a notification from Hammad Hassan where we don't have to second guess anything - that would be nice. Of course it would be even nicer if the international community would recognize that there should be an "ombudsman" (or office) of timezone issues, to which each country must inform about their plans for time changes, or else ... Of course, I'm dreaming, that will never happen, and I guess it's just like human rights etc. the countries that will respond (and report time changes some time before they happen) are the ones that are already doing it correctly, and in an organized manner. Regards, - Jesper -----Original Message----- From: Robert Elz [mailto:kre@munnari.OZ.AU] # The eve of a day is not the same as the evening of the day, it means the # day before the day concerned (hence Christmas Eve is Dec 24 ...)

Early DST in Uruguay
by Jesper Norgaard Welen Sept. 7, 2006

Sept. 7, 2006

Gentlemen (and women), we have an early definition of perpetual DST in Uruguay. The government of Uruguay wants to be predictable ... grin 8-) ... at least in timezone matters. The web page http://www.presidencia.gub.uy/_web/decretos/2006/09/09_2006.htm states that "04/09/06 - SE ADELANTA LA HORA OFICIAL A PARTIR DE LA HORA 02:00 AM DEL PRIMER DOMINGO DEL MES DE OCTUBRE DE CADA AÑO. DEC. N° 311/006" translation "04/09/06 - official time will be advanced at 2:00 AM of the First Sunday of October of every year". It links to http://www.presidencia.gub.uy/_web/decretos/2006/09/CM%20210_08%2006%202006_ 00001.PDF which have the following 4 points: I) that the (DST) measure is meant to produce conditions for a saving of energy and an improvement in the daily use (of electricity) and a displacement of the peak of summer electricity use. II) that it is convenient for all involved, to consolidate a periodic and predictable system of this adjustment of clocks. III) that for the above reasons the official time will be adjusted to the period 2:00 AM of the First Sunday of October and 2:00 AM of the Second Sunday of March each year. IV) that the proposed measure will become an important energy saving. Especially I like the second point, there are unfortunately few governments that don't have a predictable timezone system yet, which convert to a predictable system where timezone changes can be calculated into the future, well, at least in theory. I will not go into the details of how the Uruguay rule in the southamerica file should be changed, except that for 2006 and perpetually DST starts "Oct Sun>=1" and ends "Mar Sun>=8".
