The point is not about choosing a timezone from a location, but rather being able to show the cities linked to the timezones on a map so that end users can pickup their timezone visually.
If you're doing that, you should be showing the area on the map, not a circle around the most-populous city.
The other alternative for end users to select a timezone, is to present them with all timezones matching their country (using ISO 3166).
A third option is to ask them "what time is it right now?" and then list (or show on a map) all the zones that have the same offset. -- Clive D.W.
