Recent conversions of zones to aliases
by Stephen Colebourne Nov. 17, 2014

Nov. 17, 2014

Just to note my continued unhappiness with the conversions of zones to aliases. The recent change to map Harare to Maputo broke a test in Joda-Time (the most widely used 3rd party library in Java for date/time, probably used by millions of developers). This means that the many users of Joda-Time will get errors when they try to recompile the latest jar file, a process that has worked fine for years. In order to make the test pass I now have to special case to say that either Harare or Maputo is a valid value. This issue occurs because Joda-Time normalises all aliases to the actual zone as per TZDB data. Thus a request for DateTimeZone zone = DateTimeZone.forID("Africa/Harare"); which use to return a zone with the ID "Africa/Harare" now returns "Africa/Maputo". This means that users can no longer get a zone that represents their country for half of Africa and the Carribean. I cannot stress enough that these utterly unecessary changes have and will continue to cause observable differences in end-user applications. I remain firmly of the opinion that there should be at least one actual Zone entry for each ISO defined territory/country, and that these recent changes should not be described as minor tidying.

[tz-announce] 2014j release of tz code and data available
by Paul Eggert Nov. 12, 2014

Nov. 12, 2014

The 2014j 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 current and future time stamps Turks & Caicos' switch from US eastern time to UTC-4 year-round did not occur on 2014-11-02 at 02:00. It's currently scheduled for 2015-11-01 at 02:00. (Thanks to Chris Walton.) Changes affecting past time stamps Many pre-1989 time stamps have been corrected for Asia/Seoul and Asia/Pyongyang, based on sources for the Korean-language Wikipedia entry for time in Korea. (Thanks to Sanghyuk Jung.) Also, no longer guess that Pyongyang mimicked Seoul time after World War II, as this is politically implausible. 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: Africa/Addis_Ababa, Africa/Asmara, Africa/Dar_es_Salaam, Africa/Djibouti, Africa/Kampala, Africa/Mogadishu, Indian/Antananarivo, Indian/Comoro, and Indian/Mayotte. Changes affecting commentary The commentary is less enthusiastic about Shanks as a source, and is more careful to distinguish UT from UTC. Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2014j.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2014j.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2014j.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2014j.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.
