In that case your approach is broken.

While I'm not aware of anywhere that has shifts both backwards and
forwards from "standard time", I have no faith that politicians won't do

For example, imagine an Islamic country decides to move forwards an hour to
be in line with a major trading neighbour. So their standard time is UTC+3
and their summer time is UTC+4. But for Ramadan they still need to be close
to local solar time, so that's UTC+2. Yes, this is a hypothetical, but it's
not completely implausible.
