Answer 1

Firstly you need to download the .csv file which will provide you country/cities/timezone/region. Using this file we can display the list of countries and their cities. When user select any city we need to map it with the respected country and then this country needs to be map with device's timezones([NSTimeZone knownTimeZoneNames];).
