Brazil elections and postponed DST start
by Steffen Thorsen Oct. 4, 2006

Oct. 4, 2006

It is election time in Brazil again, and since it seems that they still cannot handle a time change in the middle of two rounds of election, they are postponing this year's start date to the weekend after the election, 2006-11-05. It appears that the decree is still not published, but that this change is very likely to happen. Source: http://jc.uol.com.br/tvjornal/2006/09/18/not_107666.php (In Portuguese) Auto-translated: It is practically certain that the schedule of summer of this year will start from the zero hour of day 5 of November, in the first turn as weekend after of the elections. Sources of the government had said that already they are finishing the details of the decree that will establish the change in the clocks. Best regards, Steffen Thorsen

DST change in Nicaragua one hour late
by Jesper Norgaard Welen Sept. 30, 2006

Sept. 30, 2006

The precidency of Nicaragua has emitted a decree 63-2006 about end of DST which means that according to my time and that of Steffen Thorsen, the change will occur an hour earlier at 1:00 (we had 2:00), but an hour later according to the 2006l tz database, which has the change to occur 0:00 at the moment. http://www.presidencia.gob.ni/buscador_gaceta/BD/DECRETOS/2006/D-063-2006P-P RN-Cambio-Hora.pdf My informal translation runs: The natural sun time is restored in all the national territory, in that the time is returned one hour at 01:00 am of October 1 of 2006. This probably means that the rule should be split from Rule Nic 2005 2006 - Oct Sun>=1 0:00 0 S to Rule Nic 2005 only - Oct Sun>=1 0:00 0 S Rule Nic 2006 only - Oct Sun>=1 1:00 0 S Regards, - Jesper Jesper Nørgaard Welen Email: jnorgard(a)Prodigy.Net.mx Project Leader (Líder de Proyecto) Software CIMMYT - Centro Internacional de Mejoramiento de Maíz y Trigo Dirección: CIMMYT Int. c/o Jesper Nørgaard Km. 45, Carretera México-Veracruz El Batán Texcoco, Edo. de México CP 56130 MEXICO Tel.: +52 (55) 58-04-20-04 ext. 1374 Fax: +52 (55) 58-04-75-58 Tel.

After a transition, the described effect on zone offset and abbreviation *remain* in effect until the next transition. The "TO" part of a rule is used to enable a shorthand for a _recurring_ transition, such as "first Tuesday of February", for all years within the range. If "to" is "only", then the *transition* being documented is a singleton, but the transitioned-into offset/abbreviation remains in effect until the _next_ transition, no matter how far in the future. > There are other failures in the parsing.

If a Zone refers to a time within a Rule that is before the first transition mentioned for that rule, then the _oldest_standard_time_ "Letter/s" is used.

Confusing: granted. Whether "Until" is one or multiple fields is a matter of interpretation. The _traditional_ understanding is that it is a *single* "timestamp field" which may happen to have spaces within it. BTW the subfields aren't "YEAR IN ON AT", but "YEAR MONTH DAY TIME". In this regard, a recent addition to the tzcode tarball is zoneinfo2tdf.pl, which translates the more free-with-spaces zone tzdata into a form which strictly uses a single tab between fields. This may make life easier for some by simplifying their parser's requirements. (Or not.) --Ken Pizzini

RE: Question on abbreviations

Then I'm confused. At the end of 1942, that rule should expire, because of the "only" leaving what rule in effect? Apparently none, leaving the time in 1943 undefined. Where can I find a explanation of the tz text database format?

Yes, that's what's happening here. The rule to switch to DST applies only in 1942. There is no rule to switch _out_ of DST in 1942, so DST continues until 1945, the next rule that applies. >> Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S >> > ... >> > Rule US 1942 only - Feb 9 2:00 1:00 W # War >> > Rule US 1945 only - Aug 14 23:00u 1:00 P #
