Definition for timezone Asia/Urumqi and Asia/Kashgar, CST, and other questions about Chinese timezones.
by gfb hjjhjh Jan. 5, 2017

Jan. 5, 2017

1. Currently, Asia/Urumqi and Asia/Kashgar are defined as UTC+6, covering most of Xinjiang and Tibet. However, from brief search result, I cannot see any indication about the UTC+6 usage by ethnic non-han in Xinjiang also exists in Tibet, and Lhasa resident daily activities are apparently only one hours later than those in inner China too. The official announcement about UTC+6 usage in Xinjiang also does not cover Tibet. Thus it seems like those UTC+6 timezones in tz database should not cover Tibet. However, there might be some undocumented official announcement or on the ground usage that I does not notice and require further validation. 2. Actually, which file define the boundary of timezones in tz database? I see they are in comments for China but how about generally? 3. And given Asia/Urumqi is currently defined differently from Asia/Shanghai, and Maoming, Guandong is now using UTC+8, no matter what historical reason might be behind the consideration of putting Maoming, Guangdong in Asia/Urumqi, its current time usage along should have justified putting it in Asia/Shanghai instead 3.a. In http://mm.icann.org/pipermail/tz/2006-July/013704.html , it said Maoming and etc. are in Xinjiang tinezone with data from astro.com but I cannot find anywhere on the site that include historical timezone info and what are their sources? 4. as the name "Central Standard Time" in China was created by ROC, the current main use of this term is for the time in Taiwan and thus it might be unsuitable to use the name for timzone in mainland china area. 5. Why there are 5 different zones in China when the theory file say "if all the clocks in the region have agreed since 1970, don't bother to inclide more than one location even if subregions' clocks disagreed before 1970" ?

zdump broken with -DUSE_LTZ=0
by Joseph Myers Dec. 21, 2016

Dec. 21, 2016

I tried updating the copy of tzcode in glibc. I found that as of the latest release and current git, zdump doesn't build with -DUSE_LTZ=0, because that configuration disables the inclusion of private.h, which defines the INITIALIZE macro which zdump now uses unconditionally. (There's also a -Wundef issue with the "#if !HAVE_POSIX_DECLS", as that's also only defined in private.h, but that's easy to work around.) -- Joseph S. Myers joseph(a)codesourcery.com

Proposal: validation text file with releases
by Jon Skeet Dec. 19, 2016

Dec. 19, 2016

Background: I'm the primary developer for Noda Time <http://nodatime.org> which consumes the tz data. I'm currently refactoring the code to do this... and I've come across some code (originally ported from Joda Time) which I now understand in terms of what it's doing, but not exactly why. For a little while now, the Noda Time source repo has included a text dump file <https://github.com/nodatime/nodatime/blob/master/src/NodaTime.Test/TestData…>, containing a text dump of every transition (up to 2100, at the moment) for every time zone. It looks like this, picking just one example: Zone: Africa/Maseru LMT: [StartOfTime, 1892-02-07T22:08:00Z) +01:52 (+00) SAST: [1892-02-07T22:08:00Z, 1903-02-28T22:30:00Z) +01:30 (+00) SAST: [1903-02-28T22:30:00Z, 1942-09-20T00:00:00Z) +02 (+00) SAST: [1942-09-20T00:00:00Z, 1943-03-20T23:00:00Z) +03 (+01) SAST: [1943-03-20T23:00:00Z, 1943-09-19T00:00:00Z) +02 (+00) SAST: [1943-09-19T00:00:00Z, 1944-03-18T23:00:00Z) +03 (+01) SAST: [1944-03-18T23:00:00Z, EndOfTime) +02 (+00) I use this file for confidence when refactoring my time zone handling code - if the new code comes up with the same set of transitions as the old code, it's probably okay. (This is just one line of defence, of course - there are unit tests, though not as many as I'd like.) It strikes me that having a similar file (I'm not wedded to the format, but it should have all the same information, one way or another) released alongside the main data files would be really handy for *all* implementors - it would be a good way of validating consistency across multiple platforms, with the release data being canonical. For any platforms which didn't want to actually consume the rules as rules, but just wanted a list of transitions, it could even effectively replace their use of the data. One other benefit: diffing the dump between two releases would make it clear what had changed in *effect*, rather than just in terms of rules. One sticking point is size. The current file for Noda Time is about 4MB, although it zips down to about 300K. Some thoughts around this: - We wouldn't need to distribute it in the same file as the data - just as we have data and code file, there could be a "textdump" file or whatever we'd want to call it. These could be retroactively generated for previous releases, too. - As you can see, there's redundancy in the format above, in that it's a list of "zone intervals" (as I call them in Noda Time) rather than a list of transitions - the end of each interval is always the start of the next interval. - For zones which settle into an infinite daylight saving pattern, I currently generate from the start of time to 2100 (and then a single zone interval for the end of time as Noda Time understands it; we'd need to work out what form that would take, if any). If we decided that "year of release + 30 years" was enough, that would cut down the size considerably. Any thoughts? If the feeling is broadly positive, the next step would be to nail down the text format, then find a willing victim/volunteer to write the C code. (You really don't want me writing C...) Jon

Havranek et al. on DST's effect on energy consumption
by Paul Eggert Dec. 18, 2016

Dec. 18, 2016

A recent meta-analysis of energy savings due to daylight-saving time found a mean effect close to zero (the weighted mean of 0.343% was less than the estimated standard error). The largest energy savings from DST was found in high-latitude countries; areas closer to the equator tended to have negative energy savings. Studies published in journals with high impact factors tended to be more pessimistic about energy-savings benefits. The study concluded, "the effects of daylight saving time on energy consumption are too small to justify the biannual time-shifting." Havranek T, Herman D, Irsova Z. Does daylight saving save energy? a meta-analysis. MPRA Paper No. 74518 (2016-10-12). https://mpra.ub.uni-muenchen.de/74518/1/MPRA_paper_74518.pdf

Re: [tz] Request to add entry to "Programmatic interfaces that map geographical coordinates"
by Evan Siroky Dec. 17, 2016

Dec. 17, 2016

The package tz-lookup and geo-tz are independent of each other. As far as I know, the major difference between the two is the data source that is used. geo-tz is released under the MIT license. Feel free to link to the timezone tag. Although in my opinion a lot of the packages aren't the best because they don't get updated frequently enough with changes to the timezone db.

Ecuador DST in 1992/93
by Alois Treindl Dec. 15, 2016

Dec. 15, 2016

A client born in Ecuador wrote to me: "I need a little help with something plus I don't know who else can help me besides Astro! When I was born, the President of Ecuador changed the time zone (one hour ahead) from Nov/28/1992 to Feb/05/1993 because of problems with energy and there were a lot of power cuts across the country. " I checked the tzdata/southamerica file which holds for Ecuador: # Ecuador # # Milne says the Central and South American Telegraph Company used -5:24:15. # # From Paul Eggert (2007-03-04): # Apparently Ecuador had a failed experiment with DST in 1992. # <http://midena.gov.ec/content/view/1261/208/> (2007-02-27) and # <http://www.hoy.com.ec/NoticiaNue.asp?row_id=249856> (2006-11-06) both # talk about "hora Sixto". Leave this alone for now, as we have no data. # # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Guayaquil -5:19:20 - LMT 1890 -5:14:00 - QMT 1931 # Quito Mean Time -5:00 - ECT # Ecuador Time The two links in the comment to not work. I search the web and came up with this link: http://www.elcomercio.com/actualidad/hora-sixto-1993.html which says: Al inicio de su mandato, el Gobierno Nacional, mediante Decreto Presidencial no. 285, obligó que todos los ecuatorianos adelantaran una hora en sus relojes para “ aprovechar la luz solar” y disminuir el consumo de energía. Fue la llamada ‘hora de Sixto’, que se aplicó desde el 28 de noviembre de 1992 hasta el 5 de febrero de 1993. Incluso, los estudiantes de todos los niveles educativos estuvieron obligados a iniciar clases a las 06:00 y terminar antes del mediodía. Google translation: At the beginning of his term, the National Government, through Presidential Decree no. 285, forced all Ecuadorians to advance an hour in their watches to "take advantage of sunlight" and reduce energy consumption. It was the so-called 'Sixtus hour', which was applied from November 28, 1992 until February 5, 1993. Even students of all educational levels were forced to start classes at 06:00 and finish before midday. There should probably be a rule: Rule ECU 1992 only - Nov 28 0:00 1:00 S Rule ECU 1993 only - Feb 5 0:00 0 - and the last lines of the existing entry should refer to this rule. Whether the law applied also to Galapagos, I do not know.

Zone name policy
by Maksym Besida Dec. 2, 2016

Dec. 2, 2016

Hello, In all versions of TZ data Ukraine zones are named using Russian language transliteration (e.g Europe/Kiev, Europe/Uzhgorod, Europe/Zaporozhye). In *tzdata2016j* in file *europe *it is said *"Kyiv is the transliteration of the Ukrainian name, but "Kiev" is more common in English".* But this is a mistake, because *"more common"* is a very subjective measure and in this case is imposed by russian speaking community which is larger than ukrainian one. Believe that in most groups of Chinese language the mentioned names are pronounced differently from Russian transliteration(even if chinese speaking population is greater than russian one). The official language in Ukraine is Ukrainian, so the proper names of mentioned cities are Kyiv, Uzhhorod and Zaporizhia respectively. Who is responsible for editing this data? -- Regards, Maksym Besida.

Doubt about releases/updates
by Pablo Sánchez Dec. 1, 2016

Dec. 1, 2016

Greetings, everyone! I have a doubt about the TZ database release or updates, and maybe you can help me to solve it. So, is the database update BEFORE or AFTER a new DST has started? The reason why I need to know it is because we are having issues about calculating some ETAs and presenting the information on reports, because PHP internal database doesn't get updates automatically. So we decided to use an extension that uses IANA's Timezone Database (updated approximatelly 23 times an year). So, we need to know if those updates are released before the daylight saving time starts or if you release it before it starts. Since there are usually political decisions that delays or rushes the DST beginning, I believe those updates comes prior to the actual fact, with a data on wich day begin, so I should not worry on using the extension that updates itself with 24 hours delay, right? So, do you update it before DST comes, or after? -- *Pablo Santiago Sánchez* ZCE ZEND006757 phackwer(a)gmail.com (61) 9843-0883 http://www.sansis.com.br *"Pluralitas non est ponenda sine necessitate"*

[tz-announce] 2016j release of tz code and data available
by Paul Eggert Nov. 24, 2016

Nov. 24, 2016

The 2016j release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Briefly: Saratov, Russia moves from +03 to +04 on 2016-12-04. Changes to future time stamps Saratov, Russia switches from +03 to +04 on 2016-12-04 at 02:00. This hives off a new zone Europe/Saratov from Europe/Volgograd. (Thanks to Yuri Konotopov and Stepan Golosunov.) Changes to past time stamps The new zone Asia/Atyrau for Atyraū Region, Kazakhstan, is like Asia/Aqtau except it switched from +04/+05 to +05/+06 in spring 1999, not fall 1994. (Thanks to Stepan Golosunov.) Changes to past time zone abbreviations Asia/Gaza and Asia/Hebron now use "EEST", not "EET", to denote summer time before 1948. The old use of "EET" was a typo. Changes to code zic no longer mishandles file systems that lack hard links, fixing bugs introduced in 2016g. (Problems reported by Tom Lane.) Also, when the destination already contains symbolic links, zic should now work better on systems where the 'link' system call does not follow symbolic links. Changes to documentation and commentary tz-link.htm now documents the relationship between release version numbers and development-repository commit tags. (Suggested by Paul Koning.) The 'Theory' file now documents UT. iso3166.tab now accents "Curaçao", and commentary now mentions the names "Cabo Verde" and "Czechia". (Thanks to Jiří Boháč.)
