I'm creating a software calculator project, and I'd like my users to be able to convert between time zones using what they're familiar with: country, or city/ state names.
So I need to convert from these places to the corresponding Windows time zone, and have been looking for a database online to do so, without success.
What I have been able to find is a way to convert from TZID (Olsen) to Windows timezone IDs using this URL: http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/zone_tzid.html
So maybe there's a database which maps all the places of the world to TZID, and then I would use a two-step process instead of one.
Any help would be much appreciated. When I say 'database', even just a HTML page would do, and then I can extract the right info.
There's a shapefile by Eric Muller which tries to capture the boundaries of all the tzdata timezones in the world as (spherical) polygons: http://efele.net/maps/tz/world/ It should be fairly accurate for population centres but maybe not so much for outback regions close to the boundaries. -- -=( Ian Abbott @ MEV Ltd.
