The subject of determining the correct time zone for any city has come up

If so, does anyone know of a good source for long/lat data for major/minor
cities? Is this even possible to achieve? Is there a better way?
And, I'm only interested in current time/time zone mapping and not worried
about historical data, in case that might make the task any easier.
