The history of timezones has some existing cases where a specific timezone has been renamed. For example, the Asia/Calcutta timezone has been deemed obsolete and replaced by Asia/Kolkata.
In Ukraine, according to international standards, there is a timezone called Europe/Kiev. The capital of Ukraine is officially called "Kyiv". "Kiev" is an incorrect version that emerged a long time way before a Soviet Union collapsed in 1991.
We have a really large community of programmers, that would like to start the process of renaming the Europe/Kiev timezone to Europe/Kyiv. We understand that it will take a long time for everybody to transition, but it has to be done in the long term.
Where and how do we put this suggestion so it can be reviewed by the people who officially rule timezone names?
Time Zone Database (tzdata) is managed by Iana, the Internet Assigned Numbers Authority.
The suggestion to rename the time zone ID Europe/Kiev to Europe/Kyiv has been made and accepted! The change was introduced in release 2022b (Released 2022-08-11).
From a software point of view, this is a breaking change that could have been managed much better with a transition period where both time zone identifiers exist and the old is deprecated.
Unfortunately, the release is now out. Softwares are starting to include the new tzdata and both IDs appear in systems creating unexpected bugs. If you manipulate time zone IDs, I would suggest people adding a condition to support both time zone IDs for a transition period that could last many months.
