subj. Please update ICU/tz libraries to latest version, or make according changes in FW. https://en.wikipedia.org/wiki/Kyiv
Please repot this to the maintainer of tzdb.
If there will be official changes made, they will come to RouterOS automatically.
MikroTik does not invent timezones. They have official names and they come from IANA
latest version of IANA database (TZDB) time zones version 2022b that includes the change of Europe/Kiev to Europe/Kyiv (note the old name still remains as alias).
P.S. But I get your point. Thanks.
The latest tzdb is 2022g
