Turkey name change
by Letu Yang Sept. 7, 2023

Sept. 7, 2023

I understand this has been discussed last year, but since then both UN and US had adopted the name change from “Turkey” to “ Türkiye”. https://turkiye.un.org/en/184798-turkeys-name-changed-t%C3%BCrkiye Turkey's name changed to Türkiye turkiye.un.org https://www.nytimes.com/2023/01/05/world/middleeast/turkey-spelling-change.… For the State Department, Now It’s Türkiye, Not Turkey nytimes.com Recently Unicode CLDR data has updated the name in CLDR 43 as well. https://cldr.unicode.org/index/downloads/cldr-43 The Turkish government recently asked businesses operating in Türkiye to adopt the new name before the end of the 2023. I think it might be the time for the Turkey Time to be changed to Türkiye Time in tzdata. Letu Yang

Re: [tz] Time zone of Mongolia
by Phake Nick Sept. 1, 2023

Sept. 1, 2023

Dear Delgermaa, Specifically when it come to Mongolia, in addition to what have been mentioned by others about start time of DST, can you help confirm status of standard time that have been used across the country now and in the past? Since DST would have to depend on correct standard time information, and despite crrently tz database have tried to use different information sources to figure out what time have been used by different parts of Mongolia, some of the information are in conflicts. Is it correct that currently western part of Mongolia use UTC+7 while rest of the country use UTC+8? And is it correct that Eastern part of the country used UTC+9 in the past but switched to UTC+8 sometimes before year 2008? If this is the case do you know when this happened? Also do you know what's the background of some information from year 2005 claiming that Sükhbaatar Aimag used UTC+8.5 that year? And is there anywhere official where these information can be sourced? Best Regards, Nick.

[PATCH] Improve touches when making tarballs

* Makefile (SET_TIMESTAMP_N, set-timestamps.out) (tzdata$(VERSION)-rearguard.tar.gz, tzdata$(VERSION)-tailored.tar.gz): Do not use ‘touch -c’, as POSIX says it exits with status 0 even when it fails.
