Timezone correction
by Carlos Bergero Oct. 1, 2006

Oct. 1, 2006

Due to presidential resolution Nº 1041/006 the time in Uruguay has been set to use a local summer time to save power, we still remain at time zone -3:00. Starting the first Sunday of October 2006 at 2:00 am clocks around the country should be set one hour ahead. In the 2nd Sunday of March, the following year, at 2:00 am clocks should be set back to the correct time. I had set the rules in the following manner, for now they work fine. Rule Uruguay 2006 max - Oct Sun>=1 2:00 1:00 S Rule Uruguay 2007 max - Mar Sun>=8 2:00 0 - A/P Carlos Bergero Servicio de Informática Facultad de Ciencias, U. de la R.

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.

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

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.

Yes, that's what's happening here. The rule to switch to DST applies only in 1942.

There is also the original issue of %s being null in 1943. This seems to be a bug. But maybe not. I'm unable from the documents I've seen to determine the intended behavior. None the less, it seems obvious to me that either both the time resulting from the transition and the letter carry forward or neither one does. Have one but not the other carry forward seems nonsensical. ++PLS ________________________________ From: tz-request(a)elsie.nci.nih.gov [mailto:tz-request@elsie.nci.nih.gov] On Behalf Of Mark Davis Sent: Wednesday, September 27, 2006 4:14 PM To: tz(a)lecserver.nci.nih.gov Cc: tz(a)lecserver.nci.nih.gov Subject: Re: Question on abbreviations My reading of the specification (zic.8.txt) was that the first rule mentioned was operative during the interval from 1942 to "only", that is, during 1942 alone.

In addition to minimum and maximum (as above), the word only (or an abbreviation) may be used to repeat the value of the FROM field.

Question on abbreviations
by Mark Davis Sept. 27, 2006

Sept. 27, 2006

I'm getting 3 strange cases when parsing the tz database, for the following cases: - Didn't find %s values for M%sT under America/Phoenix:US for 1944 to 1944 - Didn't find %s values for C%sT under Asia/Macau:PRC for 1999 to +INF - Didn't find %s values for CE%sT under Europe/Warsaw:Poland for 1922 to 1940 Let's take the first case. In the file northamerica, we have the following lines. Zone America/Phoenix -7:28:18 - LMT 1883 Nov 18 11:31:42 -7:00 US M%sT 1944 Jan 1 00:01 -7:00 - MST 1944 Apr 1 00:01 -7:00 US M%sT 1944 Oct 1 00:01 -7:00 - MST 1967 -7:00 US M%sT 1968 Mar 21 -7:00 - MST Now, according to my reading of zic.8.txt, to see what the values for %s are, we look at the rules that are in effect for the period in question. So for the 2nd occurence of M%sT, we are concerned with the time between 1944 Apr 1 00:01 UNTIL 1944 Oct 1 00:01, according to the US rules. In the Rule documentation, we have: LETTER/S Gives the "variable part" (for example, the "S" or "D" in "EST" or "EDT") of time zone abbreviations to be used when this rule is in effect. If this field is -, the variable part is null. So to get the value, we should look at the US rule that is in effect during 1944. Here are the US rules: # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule US 1918 1919 - Mar lastSun 2:00 1:00 D Rule US 1918 1919 - Oct lastSun 2:00 0 S Rule US 1942 only - Feb 9 2:00 1:00 W # War Rule US 1945 only - Aug 14 23:00u 1:00 P # Peace Rule US 1945 only - Sep 30 2:00 0 S Rule US 1967 2006 - Oct lastSun 2:00 0 S Rule US 1967 1973 - Apr lastSun 2:00 1:00 D Rule US 1974 only - Jan 6 2:00 1:00 D Rule US 1975 only - Feb 23 2:00 1:00 D Rule US 1976 1986 - Apr lastSun 2:00 1:00 D Rule US 1987 2006 - Apr Sun>=1 2:00 1:00 D Rule US 2007 max - Mar Sun>=8 2:00 1:00 D Rule US 2007 max - Nov Sun>=1 2:00 0 S None of them are operant during 1944, so I don't find any value for M%sT. Am I misreading something?

proposed tz data changes for Egypt, Syria, Uruguay (revised)

Sept. 20, 2006

Here is the latest set of proposed changes for Egypt, Syria, and Uruguay. This supersedes the two messages I sent out earlier on this subject in <http://article.gmane.org/gmane.comp.time.tz/1224> and <http://article.gmane.org/gmane.comp.time.tz/1221>. I'd like to thank Steffen Thorsen, Oscar van Vlijmen, and Jesper Norgaard Welen for reading and correcting the earlier messages. This change affects time stamps within the next 48 hours in Egypt and Syria, so people interested in up-to-date correctness in those regions need to apply this patch soon. =================================================================== RCS file: RCS/africa,v retrieving revision 2006.12 retrieving revision 2006.12.0.1 diff -pu -r2006.12 -r2006.12.0.1 --- africa 2006/09/18 16:58:11 2006.12 +++ africa 2006/09/20 19:35:29 2006.12.0.1 @@ -212,35 +212,13 @@ Rule Egypt 1990 1994 - May 1 1:00 1:00 # Go with IATA starting in 1995, except correct 1995 entry from 09-30 to 09-29.
