There aren't any geocoding modules in the Perl DateTime suite (why would
there be?), but there *are* plenty of geocoding Perl CPAN modules. Check out
the Geo::Coder::* modules, for example.

If you want to roll your own simple time zone aliases, check out
DateTime::TimeZone::Alias:


    http://search.cpan.org/dist/DateTime-TimeZone-Alias/

The simplest DIY solution is a lookup table using a hash.

If you want to do something more elaborate, there are oodles of
geocoding resources for programmers on the web:
