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.)

Two problems: - one language product with two sources of time information - no wonder the OP is confused why their time is wrong: perhaps you could post how the OP can correct their Joda time, walk them thru difficulties that may be encountered in http://www.joda.org/joda-time/tz_update.html; - Joda time says the project is finished, and advises migration to Java SE 8 java.time, so it may not be reasonable to expect prompt future releases or tz updates. Like Adobe products, Java has become such a source of security holes and vulnerabilities requiring frequent updates, blocked by various products, that it's safer to uninstall them, eliminate the annoyances and vulnerabilities, and do without what they provide, or use alternatives that don't suffer the same issues. -- Take care.

Hello. Today Russian Duma has approved in 1st read (of 3) Law project №1058438-6 that will move Saratov region to UTC+4.

As I think new timezone "Europe/Saratov" should be created in tzdata. I will inform you as soon as President will approve Law project. -- Best regards, Yuri Konotopov

[PATCH] Minor changes to iso3166.tab
by Jiri Bohac Nov. 17, 2016

Nov. 17, 2016

As noted in the file, the table intentionally differs from the ISO 3166 English names, mostly using even shorter names than the official short name. In a few cases, it seems to be out of sync with ISO for no good reason: Official changes in ISO, where new is same length or shorter than original: Cape Verde -> Cabo Verde Czech Republic -> Czechia UTF-8 now used elsewhere, so why not for Curaçao: Curacao -> Curaçao No good reason to differ from the standard?: Macau -> Macao Personally, I would also change "Britain" to "United Kingdom", I think it's where people would look first. But it would go from shorter to longer, so I did not include it in the patch. It's still much shorter than many other names. Would "United Kingdom" make sense here? --- iso3166.tab | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/iso3166.tab b/iso3166.tab index 7a8df2c..0e07afd 100644 --- a/iso3166.tab +++ b/iso3166.tab @@ -74,11 +74,11 @@ CN China CO Colombia CR Costa Rica CU Cuba -CV Cape Verde -CW Curacao +CV Cabo Verde +CW Curaçao CX Christmas Island CY Cyprus -CZ Czech Republic +CZ Czechia DE Germany DJ Djibouti DK Denmark @@ -170,7 +170,7 @@ MK Macedonia ML Mali MM Myanmar (Burma) MN Mongolia -MO Macau +MO Macao MP Northern Mariana Islands MQ Martinique MR Mauritania -- Jiri Bohac <jbohac(a)suse.cz> SUSE Labs, SUSE CZ

Hungary considers moving to +02 year-round
by Paul Eggert Nov. 17, 2016

Nov. 17, 2016

A bill to put Hungary on permanent EET (+02) has passed a parliament committee unanimously. The full parliament is scheduled to vote on it next week. Presumably this would require coordination with the EU, which may mean delays before the change would take effect. See: End of Hungaro-pessimism? - the times they are changing in the Hungarian Parliament.

tzdata2016g missing version information
by Howard Hinnant Nov. 12, 2016

Nov. 12, 2016

As is known, the version number no longer appears in the Makefile. The release notes in NEWS say: > To support the more-accurate version number, its > specification has moved from a line in the Makefile to a new > source file 'version’. The version file does not appear in the uncompressed tzdata2016g database. This is hurting my ability to report the version of the database to my clients. Can we please put a version file in the database? Howard

Re: [tz] tzdata2016g missing version information

That assumption was never documented or guaranteed and is no longer valid. >Perhaps you can work around the problem by modifying the Makefile to say "VERSION = 2016g" (I don't have the Oracle software and so can't easily test this). >We are discussing a better way to address this problem in the future. @Paul Eggert: The Oracle Timezone Update Tool can be downloaded from here: http://www.oracle.com/technetwork/java/javase/documentation/tzupdater-readm…. This tool has two ways of updating the timezone database: 1. Online where the timezone database is downloaded from: -l http://www.iana.org/time-zones/repository/tzdata-latest.tar.gz 2. Offline where the timezone database is loaded locally: -l file:///tmp/tzdata2016g.tar.gz The tzdata file published on the IANA site needs to include the VERSION information so that this tool can work. When do you think this can be provided? I need to test the Oracle Timezone Updater Tool as soon as possible because I have customers with critical systems dependent on the time zone database. @Susan Abraham: I don't know if you are involved with the Timezone Updater Tool but this tool currently can't update the timezone because the database doesn't contain the VERSION information. @Kim Davies: I am adding you to keep you directly in the loop.

Failed to update tzdata2016g and higer with tzupdater
by Sawadee.Prakayphetchara＠thomsonreuters.com Nov. 9, 2016

Nov. 9, 2016

Hi, We found an issue when try to update timezone with the tzdata2016g.tar.gz - tzdata2016i.tar.gz The problem is that VERSION in the Makefile is not correct, the correct value should match with tz version i.e. 2016i not unknown. # Version number for the distribution, overridden in the 'tarballs' rule below. VERSION= unknown The workaround has been mention in, http://stackoverflow.com/questions/39832866/tzupdater-failing-with-tzdata20… * Update Makefile of http://www.iana.org/time-zones/repository/releases/tzdata2016g.tar.gz: Original value of VERSION variable is unknown and you need to update it to 2016g. * Regenerate tzdata2016g.tar.gz.sha512 file So far we need to apply the workaround on each release. It would be great if you can correct the version in next release? Regards, Sawadee M.
