by Mark Davis Sept. 28, 2006

Sept. 28, 2006

There are new country codes RS for Serbia and ME for Montenegro. http://www.iso.org/iso/en/prods-services/iso3166ma/03updates-on-iso-3166/nl… I would suggest the following changes: In zone.tab Change the line: CS +4450+02030 Europe/Belgrade to: RS +4450+02030 Europe/Belgrade Add: ME +4247+01928 Europe/Podgorica In europe Add: Link Europe/Belgrade Europe/Podgorica Mark

RE: Question on abbreviations

Sept. 27, 2006

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.

According to this text, if I saw the following: Rule US 1942 1944 - Feb 9 2:00 1:00 W # War The rule should not apply in 1945. So I request that the text be fixed, because the rule clearly, according to the explanations given on this thread, applies *afterwards* (and the circumstances in which it applies need to be clearly specified.

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

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?

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

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.

RE: Time zone rules change
by Jesper Norgaard Welen Sept. 15, 2006

Sept. 15, 2006

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".
