Re: SunOS and timelocal, timegm, tzsetwall
by Robbin Kawabata Jan. 16, 2008

Jan. 16, 2008

timelocal(), timegm(), tzsetwall() are no longer in SunOS. I believe they were replaced in SunOS 5.0 (by mktime(), localtime(), tzset()).

Does any one remember the logic behind sp->goback and sp->goahead in localtime.c?
by Jonathan Leffler Jan. 15, 2008

Jan. 15, 2008

AFAICT, the logic associated with sp->goback and sp->goahead in tzload() and in localsub() in localtime.c could only ever be used if there were at least 800 time change entries, enough for two per year for a 400 year cycle. And, empirically, there are no time zone definitions in the current (2007k) data set that get anywhere close to this. However, this code can't have been put in there for no reason whatsoever, so I'd like to understand what was the intention - if anybody can remember. -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

Why does localtime() call tzset() but localtime_r() not?
by Jonathan Leffler Jan. 11, 2008

Jan. 11, 2008

Actually, the subject pretty much says it all. In tzcode2007k (also in 2007h), the code in localtime.c is: struct tm * localtime(const time_t *const timep) { tzset(); return localsub(timep, 0L, &tm); } struct tm * localtime_r(const time_t *const timep, struct tm *tmp) { return localsub(timep, 0L, tmp); } I can't immediately see a justification for the asymmetry in the POSIX specification of these functions, but I could be missing something. -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

SunOS and timelocal, timegm, tzsetwall
by Jonathan Leffler Jan. 11, 2008

Jan. 11, 2008

In Makefile (for tzcode2007k), there are the comments: # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. # These functions may well disappear in future releases of the time # conversion package. For Solaris 8 (SunOS 5.8) and Solaris 10 (SunOS 5.10), neither the standard C library nor any other shared library in /lib or /usr/lib defines or references tzsetwall, timelocal or timegm -- the functions no longer exist in Solaris. I was checking on SPARC rather than Intel, but I would not expect that to matter in practice. You can, however, find references for these functions for Solaris 2.5 (aka SunOS 5.5) and Solaris 2.6 (SunOS 5.6) if you Google "site:sun.comtzsetwall" - ( 2.5: http://docs.sun.com/app/docs/doc/802-1930-03/6i5u95utq?a=view; 2.6: http://docs.sun.com/app/docs/doc/802-5747-03/6i9g1bha0?l=ko&a=view) Interestingly, there is a Solaris 8 manual page ( http://docs.sun.com/app/docs/doc/806-0627/6j9vhfn9n?l=ko&a=view) that mentions tzsetwall (but not timegm or timelocal), but I still can't find the function in any of the shared libraries on a representative Solaris 8 machine. There is a 'Solaris 8 Transition Guide' at http://docs.sun.com/app/docs/doc/805-6331/6j5vgg6bv?a=view which mentions all three - describing their replacements. -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

Shapefile for Olson time zone names
by Mark Shuttleworth Jan. 2, 2008

Jan. 2, 2008

Hi folks I'm trying to map from latitude and longitude to Olson time zone names, and haven't had any luck locating the relevant data. Does anyone know of an existing data set, in any format which I could ultimately get into PostGIS (Shapefile, or PostGIS, or anything similar), which would serve this purpose? If anyone is interested in helping to create such a data set I did find a potential starting point: this data set from BBN which is old (2002) and only maps to the UTC time offsets (+1, +2 etc): http://openmap.bbn.com/data/shape/timezone/ I would love to see such a data set becoming a standard part of the ZoneInfo repository, updated in an open fashion. If some funding would help to get that started, I'll gladly entertain proposals. Mark

Argentina adopts DST again
by Steffen Thorsen Dec. 27, 2007

Dec. 27, 2007

A user (Leonardo Chaim) reported that Argentina will adopt DST, and I have found more details on Argentina's presidential web site, as well as on many news sites. Argentina will advance clocks by one hour on 2007-12-30 00:00 to (01:00) and turn them back again on 2008-03-16 00:00 (to 23:00). It appears that all of the country (all Zone-entries) are affected. The official news report about it: (Spanish) http://www.casarosada.gov.ar/index.php?option=com_content&task=view&id=1509… which has a link to the "Comunicado"/official notice: http://www.casarosada.gov.ar/index.php?option=com_content&task=view&id=1510 translated: "The measurement will prevail in all the national territory as of the 00:00 hour of Sunday 30 of December of the present year, until the 00:00 hour of Sunday 16 of March of 2008, in that the clocks will have to retard one hour as a result of the application of the winter schedule. " News reports like http://www.lanacion.com.ar/opinion/nota.asp?nota_id=973037 indicate that Argentina will use DST next year as well, from October to March, although exact rules are not given.

Senators approved DST in Argentina
by Jesper Norgaard Welen Dec. 26, 2007

The Senate approved the DST proposal with 57 votes to 3: http://www.telam.com.ar/vernota.php?tipo=N <http://www.telam.com.ar/vernota.php?tipo=N&idPub=87422&id=201118&dis=1&sec= 1> &idPub=87422&id=201118&dis=1&sec=1 The article says that the measure is now being processed by "Deputados", to be approved today. I still haven't seen the text of the proposal that they are voting about, and especially it is not clear what is meant in news articles about "from 30.th of December" which to me would be 2007-12-30 0:00 and "starting midnight of 30.th. December" which to me means 2007-12-30 24:00 or rather 2007-12-31 0:00. I agree that without further information it is probably more likely to be 2007-12-30 0:00 as Paul Eggert has proposed for a tz database change. But the actual text of the (future) law would be helpful.

Argentinian DST
by Jesper Norgaard Welen Dec. 26, 2007

Dec. 26, 2007

There seems to be some anxiety whether the Argentinian DST goes through. The funny thing is that according to this article http://www.parlamentario.com/noticia-12594.html ... most members seem to be in favor, since this was already suggested by the opposition several times, in vain (it was rejected). On the other hand now that the government suggests it, the oppositon has refused to cooperate to gather sufficient members of Congress to vote - and apparently they can't vote without being physically present, and according to law two thirds must be present to convert this proposal into law, which is both a requirement for the the Upper (Senados) chamber and the Lower (Diputados) chamber. Apparently it's a non-issue that business and airline schedules, Operating Systems, Java, Windows Upgrade etc. etc. have to be frantically changed in very few days since we still have no definite answer. - Jesper Nørgaard Welen 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.

Time Zone File format - When does tzh_ttisgmtcnt or tzh_ttisstdcnt differ from tzh_typecnt, and how, and why?
by Jonathan Leffler Dec. 10, 2007

Dec. 10, 2007

In tzfile.5.txt, it says: tzh_ttisgmtcnt The number of UTC/local indicators stored in the file. tzh_ttisstdcnt The number of standard/wall indicators stored in the file. ... tzh_typecnt The number of "local time types" for which data is stored in the file (must not be zero). Empirically, in the tzdata2007h and tzdataj data sets, the values of tzh_ttisgmtcnt, tzh_ttisstdcnt and tzh_typecnt are always identical. Under what circumstances are there any differences in the three values? If the answer is "when the stdcnt or gmtcnt is zero", when does that happen? If the answer is "when the stdcnt or gmtcnt is a non-zero value different from typecnt", then what do the values mean? If the answer is "there isn't any difference any more, but historically, there was a transition period when they weren't all present and the stdcnt and gmtcnt were sometimes zero back then", then I can live with that as a satisfactory enough explanation. -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

Minor improvement to tzfile.5
by Jonathan Leffler Dec. 6, 2007

Dec. 6, 2007

Part way through the description of the file structure, the document says: These values serve as indices into an array of ttinfo structures that appears next in the file; these structures are defined as follows: It isn't immediately clear that there are tzh_typecnt entries in the array of ttinfo structures. Maybe the modification is as simple as: These values serve as indices into an array of ttinfo structures (with tzh_typecnt entries) that appears next in the file; these structures are defined as follows: -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

tzcode2007j.tar.gz and tzdata2007j.tar.gz
by Olson, Arthur David (NIH/NCI) [E] Dec. 3, 2007

The files... ftp://elsie.nci.nih.gov/pub/tzcode2007j.tar.gz ...and... ftp://elsie.nci.nih.gov/pub/tzdata2007j.tar.gz ...are now available. These reflect: 1. the changes circulated on the time zone mailing list to eliminate the "P" (parameter) macro; 2. the "noncontroversial" changes circulated on the time zone mailing list (less the changes to "logwtmp.c"); 3. the changes circulated on the time zone mailing list to eliminate "too many transition" errors when "min" is used in time zone rules; 4. and the changes circulated last week on the time zone mailing list by Paul Eggert (including updated information for Venezuela). --ado
