[tz-announce] 2015a release of tz code and data available
by Paul Eggert Jan. 30, 2015

Jan. 30, 2015

The 2015a 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: Changes affecting future time stamps The Mexican state of Quintana Roo, represented by America/Cancun, will shift from Central Time with DST to Eastern Time without DST on 2015-02-01 at 02:00. (Thanks to Steffen Thorsen and Gwillim Law.) Chile will not change clocks in April or thereafter; its new standard time will be its old daylight saving time. This affects America/Santiago, Pacific/Easter, and Antarctica/Palmer. (Thanks to Juan Correa.) New leap second 2015-06-30 23:59:60 UTC as per IERS Bulletin C 49. (Thanks to Tim Parenti.) Changes affecting past time stamps Iceland observed DST in 1919 and 1921, and its 1939 fallback transition was Oct. 29, not Nov. 29. Remove incorrect data from Shanks about time in Iceland between 1837 and 1908. Some more zones have been turned into links, when they differed from existing zones only for older time stamps. As usual, these changes affect UTC offsets in pre-1970 time stamps only. Their old contents have been moved to the 'backzone' file. The affected zones are: Asia/Aden, Asia/Bahrain, Asia/Kuwait, and Asia/Muscat. Changes affecting code tzalloc now scrubs time zone abbreviations compatibly with the way that tzset always has, by replacing invalid bytes with '_' and by shortening too-long abbreviations. tzselect ports to POSIX awk implementations, no longer mishandles POSIX TZ settings when GNU awk is used, and reports POSIX TZ settings to the user. (Thanks to Stefan Kuhn.) Changes affecting build procedure 'make check' now checks for links to links in the data. One such link (for Africa/Asmera) has been fixed. (Thanks to Stephen Colebourne for pointing out the problem.) Changes affecting commentary The leapseconds file commentary now mentions the expiration date. (Problem reported by Martin Burnicki.) Update Mexican Library of Congress URL. Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2015a.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2015a.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2015a.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2015a.tar.gz As usual, links to the latest release files are here: http://www.iana.org/time-zones/repository/tzcode-latest.tar.gz http://www.iana.org/time-zones/repository/tzdata-latest.tar.gz ftp://ftp.iana.org/tz/tzcode-latest.tar.gz ftp://ftp.iana.org/tz/tzdata-latest.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs.

by Juan Correa Jan. 28, 2015

Jan. 28, 2015

Although there is no formal decree yet, today the Ministry of Energy announced that Chile will drop DST, will keep "summer time" (UTC -3 / UTC -5) all year round, and will drop the Easter Island timezone (so all the Chilean land will be on a single time zone) Sources: - http://www.soychile.cl/Santiago/Sociedad/2015/01/28/301742/El-horario-de-ve… "El ministro de Energía, Máximo Pacheco, anunció la suspensión del cambio de horario, por lo que durante todo el año regirá el horario de verano. "El Gobierno ha decidido mantener en forma indefinida un horario único en Chile Continental e Insular", dijo el secretario de Estado, enfatizando "que esta medida va a ayudar a mejorar la calidad de vida de los chilenos y a ser un mejor uso de la energía"." (The ministry of Energy, Máximo Pacheco, announced the suspension of daylight saving time; so 'summer time' will rule all year round "The Government has decided to keep indefinitely the same time for Chile Continental and Easter island", pointing that "this measure will help to improve the quality of life for Chileans and use energy in a better way") - http://www.24horas.cl/nacional/ministro-de-energia-se-suspende-el-cambio-de… - http://www.t13.cl/noticia/actualidad/nacional/gobierno-suprime-cambio-de-ho… I'll share the decree as soon is published on our Diario Oficial (law gacette) -- Juan Correa Poblete PS Labs (http://www.pslabs.cl)

Jan. 28, 2015

According to this, Chile will not have a time change at all in 2015 (or beyond): http://www.gob.cl/2015/01/28/ministerio-de-energia-da-conocer-modificacione… The title translates as "Time change (Daylight Savings Time change) is suspended indefinitely". From the article continental Chile will stay at 3 hours West of GMT (GMT-3), and the islands will stay at 5 hours West (GMT-5).

The Mexican state of Quintana Roo will likely change to EST in 2015, by not going back from DST in October 2015. Its a bit unclear if they will still observe DST the years after.
