"Select your location from the map, or by region and city below."
Changing "time zone" to "location" will encourage users to make a more precise selection, and adding "below" makes it more clear that the "region and city" selection is separate from the map. Users who see the map but do not see the Region and City controls might be confused by "select your time zone... or... region and city."
