i see the idea behind it. I'm not sure if its like this in other parts of the states, but my central time shows up as chicago, which would be the closest major city as far as time goes as it is directly north, but it is about 900 miles north of us. im pretty sure chicago is the standard setting for our location as all devices that i have ever run across give us that option as the closest. i would think the best way to do it would be somehow by lat/long, but i dont really know anything about weather systems and api's outside of america.
