I think I may have found a possible solution. If you go to: http://www.world-gazetteer.com/wg.php?x=&men=gcis&lng=en&des=wg&srt=npan&col=abcdefghinoq&msz=1500&geo=-54
You can find all the cities for a certain country with their longitude/latitude. I believe it is possible to know the longitudes/latitudes for a certain timezone yes? If so then you can know all the countries and cities in a certain timezone. There is also a perl module for interfacing with the gazetteer data at: http://search.cpan.org/~lbrocard/WWW-Gazetteer-0.23/Gazetteer.pm The only problem I have now then is finding the postal codes for the cities. Any ideas on that? -Tim On Mon, Mar 24, 2008 at 1:27 PM, Harder, Paul < [EMAIL PROTECTED]> wrote: > That is not, in fact, a unique need.
