proposed time zone package changes (Samoa, Factory, et al.)
by Arthur David Olson Aug. 28, 2019

Aug. 28, 2019

Below find proposed time zone package changes; the executive summary: * Makefile Change LOCALTIME default from "Factory" to "GMT"; do not compile "factory" file (but keep it in the distribution). * Theory Remove reference to "Factory" zone. * australasia Change end of DST in Samoa in 2011 from 2011-04-03 0:00 to 2011-04-03 1:00 (thanks to Raymond Hughes for a reference). * localtime.c Initialize ttinfo structures filled by tzparse (thanks to Ravindra for reporting a valgrind warning). * zic.c Fix generation of POSIX strings for zones with rules using "weekday<=n" forms of dates (thanks to Lei Liu for finding the problem). Also, limit output for non-POSIX-specificable zones defined to follow the same rules every year. (Note that no zones of either of the above types appear in the distribution; these changes cater to add-on zones). If no problems are found, 2010n will appear on 2010-10-25. --ado diff -r -c old/Makefile new/Makefile *** old/Makefile Mon Sep 27 09:24:25 2010 --- new/Makefile Tue Oct 12 12:36:50 2010 *************** *** 1,5 **** # <pre> ! # @(#)Makefile 8.8 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)Makefile 8.9 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 12,18 **** # make zonenames # to get a list of the values you can use for LOCALTIME. !

zic changes (2/2)
by Arthur David Olson March 9, 2016

March 9, 2016

And now, the update. These changes arrange things so that binary files include "transition" entries for minimum time values; these entries eliminate localtime guesswork in handling low-valued time stamps. The bad news: binary files grow slightly as a result of these changes. The good news: there are no changes in the output of "zdump -v" applied to before-and-after versions of all the binary files generated by a "make install." Changes are attached and appear in mangled form below; these are relative to the github version of zic.c after the rollback in the earlier message today. @dashdashado 1.2 2805 lines 1.4 2813 lines *** /tmp/,azic.c 2014-05-01 01:51:36.998933800 -0400 --- /tmp/,bzic.c 2014-05-01 01:51:37.092534000 -0400 *************** *** 1480,1493 **** fromi = 0; while (fromi < timecnt && attypes[fromi].at < min_time) ++fromi; - if (isdsts[0] == 0) - while (fromi < timecnt && attypes[fromi].type == 0) - ++fromi; /* handled by default rule */ for ( ; fromi < timecnt; ++fromi) { ! if (toi != 0 && ((attypes[fromi].at + gmtoffs[attypes[toi - 1].type]) <= !

South Australia may move clocks 30 minutes
by Paul Eggert Sept. 11, 2015

Sept. 11, 2015

The South Australian government is considering changing their clocks by 30 minutes. The government would prefer advancing clocks by 30 minutes to match the time on the east coast. The public is split. Much of the resistance is coming from the west part of the state, where locals worry about their children leaving for school in the dark, and the government is prepared to consider changing school hours to address this. Another possibility is retarding clocks by 30 minutes; this would move closer to solar time, and would align better with Asia. This change would probably affect Broken Hill as well. Northern Territory will be consulted but seems less inclined to change. The consultation process will take at least two months. The government's website crashed as citizens went online to give their opinion. Sources: Nicholson M. South Australia has the most ridiculous time zone, and might be about to change it.

Re: [tz] Kyiv time zone
by sam.ua April 29, 2015

Dear Florian. perhaps you are not aware of the history between Ukraine and Russia. Let me remind you that Moscow has pursued the destruction of Ukraine, Ukrainians and the Ukrainian language and culture for many centuries. This ethnic cleansing continues today with the Russification of Ukraine. Once you destroy a nation's identity --their language, culture and history, it's quite easy to convert them into mindless robots, who are easy prey for the imperialist. Even in 1991, as we achieved our long overdue independence , Ukrane was over 80-90% pro-Russian. after two plus decades those same people, who were once slaves to the empire, have been schooled on the true history of Ukraine and understand just how devious Moscow was in it's ethnic cleansing of the Ukrainian people. Little over a year ago we got rid of the last remaining remnant of that Soviet-Russian past - the Putin puppet Yanykovych. Our cities are nearly rid of Lenin and Stalin - two monsters that murdered tens of millions of Ukrainians, but as the links you provided show, that past is still a part of the present. We are gradually getting rid of it. The issue of Kyiv vs Kiev is precisely the past vs the present. Kyiv is today, it's also what it was in the old Ruthenian-Ukrainian chronicles that date back to the 9th century. It became Kiev under Russian rule and now it's once again Kyiv. The war in Eastern Ukraine - the invasion by Russia, is a last attempt too keep Ukraine under Russia's orbit. we don't want that. My generation doesn't want that. Once again Kyiv vs Kiev is a part of that ugly past. I can promise you that all of our sites will one day be Kyiv and that the term will be the one used wide-spread and worldwide. But we need to do this one step at a time and wikipedia is a big part of this. This has to be corrected and the general population will then become familiar and accept the new word, it's very easy to spell and pronounce. I kindly ask that you respect our history, our past and what is currently happening in eastern Ukraine. it's no accident that where the Russian population - 15% of Ukraine's population. lives and breathes, there is a war. the same way Stalin killed my forefathers and replaced them with Russians from Russia, we are battling for the existence of our own unique identity. Kyiv is and will always be the proper transliterated version of our capital. there is no argument today that can supercede that. Thank you kindly, Simon Kostenko ---- On сб, 28 бер 2015 11:27:35 +0200 Florian Weimer<fw(a)deneb.enyo.de> wrote ---- * Simon: >> Many government web sites in the Ukraine still use the “Kiev” >> transliteration > For example? “While the Obama administration has publicly acknowledged it is considering supplying Kiev with arms, backed by hardline EU countries like Poland and Lithuania, German Chancellor Angela Merkel has vehemently opposed the move.” <http://www.kmu.gov.ua/control/en/publish/article?art_id=248025420>

Belarus is listed in MSK timezone
by Dzmitry Kazimirchyk April 13, 2015

April 13, 2015

I am in Belarus and I have recently noticed that my local timezone is displayed as MSK (Moscow Time) instead of FET (Further Eastearn European Time). Belarus has not made any changes to its timezone (daylight saving) policies recently, so I guess the reasoning behind this is that Russia have changed its time effectively putting its internal MSK timezone into the same time Belarus already had. However this doesn't cancel out the fact that Belarus is an independent country and it is very strange for a country to be listed under an internal timezone of some other country... Could anyone please shed some light on the reasoning behind putting Belarus into MSK timezone and if we can get our FET timezone back or at least have MSK changed to something neutral. Best regards, Dzmitry Kazimirchyk

Re: [tz] Chile TZ rule 1942 June superfluous?
by Alois Treindl April 3, 2015

April 3, 2015

I have extracted http://www.horaoficial.cl/historia_hora.html 1884 .... (irrelevant here) 1919 A partir del 1° de julio, se cambió la hora estándar, adoptando como hora oficial, la hora del meridiano del Observatorio Astronómico de Lo Espejo en Santiago, o sea, 4 horas, 42 minutos, 46,3 segundos, correspondiente a 70º 41' 34,5 " W, de Greenwich, en vez de la zona 20 del huso horario terrestre. Información difundida por el Boletín Nº 24, Aviso Nº 103/ 1919. 1927 Por Decreto Supremo N" 5.693, del 22 de agosto, se adoptaron dos horas diferentes. La hora oficial de invierno, correspondiente al meridiano 75º weste (zona +5) y la hora oficial de verano, correspondiente al meridiano 60º weste (zona +4), efectuándose los cambios el 1º de abril y el 1º de septiembre de cada año. Novedad que fue difundida por el Boletín Nº 11, por aviso Nº 56/1928. Este sistema de hora económica se vino a hacer efectivo sólo el 1º de abril de 1928. 1928 Se adquirió un cable forrado en plomo a la Compañía de Teléfonos, para conectar la Estación Horariacon la Radio Estación de Playa Ancha y a su vez con el cañón del cuartel Silva Palma. Jefe de la Estación Horaria, en esa fecha era el Sr. Cristian Wiegand O. 1941 AI cumplir el Departamento de Navegación e Hidrografía, 67 años de existencia, contaba en esa fecha la Estación Horaria con cinco relojes de alta precisión conocidos bajo el nombre de "péndulos", los cuales son controlados entre sí. De estos cinco péndulos, tres son eléctricos y dos son mecánicos en sus mecanismos de cuerda. De los tres péndulos eléctricos el principal y de mayor precisión llamado "péndulo magistral eléctrico", trabaja dentro de una campana de cobre con vidrio en su parte superior, bajo un vacío de 150 milímetros. Los otros dos péndulos eran los repetidores del magistral. 1943 El reloj de péndulo que fue destruido por el terremoto de 1906, es reconstruido totalmente y puesto en servicio por el personal de la sección Cronómetros del Departamento de Navegación e Hidrografía, reloj que seconserva en funcionamiento en este Servicio junto a otros tres de antigua data. 1946 El 27 de agosto, se publica la Ley Nº 8.522, que dispuso el cambio urgente de la hora para Santiago y la zona central del país, ante la incapacidad de las plantas de satisfacer las demandas de energía eléctrica para la industria, comercio, residencias y alumbrado público, quedando la capital y la zona central con el huso horario de +3 horas y el resto del país con un huso horario +4 horas. Boletín Nº 20, aviso Nº 380/1946, de fecha 31 de octubre de 1946. 1947 Con fecha 17 de mayo por Decreto Supremo Nº 8.777, se deroga la ley del año anterior, y se cambia la hora estándar, adoptando la hora oficial correspondiente a la zona +4 (meridiano del Observatorio de Lo Espejo, 60º weste) que rige para toda la República, a contar del 21 de mayo de 1947 a las 23 horas. Boletín Nº 10, aviso Nº 249/1947, de fecha 31 de mayo de 1947. 1959 Se procedió a la adquisición, armado e instalación, junto con la etapa de pruebas, de los relojes electrónicos de cuarzo, marca "Rhode & Schwartz", los que entraron oficialmente en servicio en 1964. -- rest irrelevant here It does contains the onset of DST rules in 1927 for 'cada ano' = each year, but no mention of a change of rules in 1932. By the way, it is interesting to note that this source confirms in the 1946 entry a division of the country into two zones, 'la capital y la zone central' and 'el resto del pais'. The capital is represented in tzdata as America/Santiago, the 'resto del pais' is not represented in tzdata, probably because the split ended before 1970. Possibly the split ended already on 21 May 1947, as it says 'zona +4 que rige para toda la Republica'.

As far as I know, an official announcement of the adoption of a new time change rule would have to appear in: http://www.diariooficial.interior.gob.cl and would also appear in: http://www.horaoficial.cl/cambio_hora.html I have been monitoring both on a daily basis, and thus far have seen nothing. So for now it's unclear to me whether this is a proposal or an announcement. -G.

about DST in Europe
by David Carrara March 31, 2015

March 31, 2015

Good day, i'm writting to you about the file "europe" taken from tzdata-latest.tar.gz I read in it : « # There shouldn't be any [current members who are not using EU rules]. # A Directive has the force of law, member states are obliged to enact # national law to implement it. The only contentious issue was the # different end date for the UK and Ireland, and this was always allowed # in the Directive. » But i think this is small imprecision. in our European official documents there is a directive saying WHEN to change but i've never seen any directive saying we had to change (each country is free). The purpose of this directive is not to have everybody changing on his own date. It's easier with only one date, the same for all. There is no real mistakes in the file, since every Member States is already applying DST for now. So it sounds like it's the same. But I think these lines in the file maintain the imprecision. Furthermore, the tzdata file says « only contentious issue was the different end date for the UK and Ireland, and this was always allowed in the Directive. » But when I read the directive I see no exception about them. They don't have same timezone, but —it's the purpose of my email— having same timezone or not is not a part of the directive. So no exception is required about them. Neither about DST observance, each country can choose to have DST or not. It's all only about the schedule, then UK and Ireland are applying their DST at the same date we do (i'm in France). They change the same day at 1am UTC. So they don't create any exception at all. AND you can read this directive (link below), there is no line about UK ; source, European's 2000/84/CE directive ; http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2001:031:0021:00… The only one exception is this line « shall not apply to the overseas territories of the Member States. » (geographical reasons) We also read in that directive that a 5 years-long schedule is made in advance. That means if anything has to change we will have to tell in advance. Thank you -- David C.

Kyiv time zone
by Simon March 27, 2015

March 27, 2015

To whom it may concern, I recently started using Ubuntu Linux on my desktop. While adding my time-zone to the parameters on the site I saw that you have "Kiev time zone". I wanted to point out that "Kiev" is an archaic transliteration of the city's name. Currently, as Ukraine is independent for close to 24 years, the proper transliteration would be "Kyiv" I kindly ask that you adopt the proper transliterated version. Kindest regards. Simon Kostenko
