The politicians make that decision.
We just need to write the software to match those decisions.
Note that even if DST changes were completely removed, then we
would still need to support it due to historical data.
I would favor abolishing DST altogether. If that means leaving the clock set
ahead of historic Standard Time settings, so be it, although the last time
that was tried in the U.S. (in the 1970s) it was a failure. People objected
to the children having to wait for morning school buses in the dark, among
other things.
The subject is politically controversial. Some claim energy savings due to
the use of DST. AFAIK there's no hard evidence to support this, at least, not
that takes into account the increase in costs due to air conditioning and
morning lighting. Certainly there are lots of claims that DST saves energy,
but for some reason no one ever seems to cite studies or methodologies to
support those claims. There is a vocal but politically disadvantaged
contingent that denies the validity of those claims.
But our infinitely wise and benevolent governments say that it must be so,
though somehow jurisdictions that don't use DST don't seem to suffer unduly
thereby. As Arne points out, dates are a matter of socio-political mandate
and our software simply must reflect the reality.
