[tz] Converting from individual cities/states/country names to Windows time zone names

[Daniel White]

Hi all,

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.
