The point is being discussed on the mailing list,
which is dedicated to time-zone software. There is an excellent
public-domain mapping from time zone names to rules; mapping lat/long
to time zone, and keeping it up to date, is the hard part.

Contrary to popular belief, there are about 400 identifiably different
timezones, without even worrying about zones which have had exactly the same
history since the Epoch (0000 Jan 1 1970 GMT).
