Re: Mapping a phone number to a timezone? (was RE: What is a time zone?)

Indeed there is! The Global Gazetteer has around 4 million places on file, and many of these include area codes and time zone data. I am currently working on trying to resolve some of the rather broad statements in the tz database, in order to assign a canonical name to each place.
