Probably a result of political changes to when DST transitions occur. We
see a new tzdata package fairly regularly because some politician somewhere
in the world decided to change when his country would switch between
standard time and DST. (It's not just Linux. All operating systems use this
package. So that Windows Patch Tuesday may be JUST for a tzdata update!)
The hardware that suffers the most is devices with fixed firmware that
can't be updated. Notably, those cheap "atomic" clocks.
So just wait a few weeks for the older clocks to switch on the day the
older laws specified.
