_If_ you could get the geographic data describing a zone (as in "what shape is it") suitable for inserting into a GIS-capable DBMS like Postgres, then you could relatively easily do queries asking what cities or postal codes are in a given time zone.

I would note that postal codes and countries are themselves shapes which could be in more than one time zone. I don't think there are any multi-zone cities, fortunately.

However, getting this data and keeping it up to date seems like a very difficult proposition.
