[arch-general] Daylight Saving Time canceled in Ukraine, will Arch know?

[Barton]

Beginning this year, Ukraine is switching to year-round DST and will
permanently reside in UTC+3 timezone (where it is now). Normally, the
switch to UTC+2 would have occurred some time in October, but no
longer.

How would Arch Linux handle it for the users who do not have NTP
configured? Would Arch somehow know not to switch the clock this year or
should zoneinfo file for Kiev be updated to reflect this change and
to avoid users' clocks being skewed?
