EarthTime will keep you up-to-date on the weather and local time from anywhere in the world.
There is an included database that contains thousands of cities, but if you don't see the city you are looking for, don't worry; you may be able to custom add that location or one that is at least close to the target.
EarthTime presents you with a color map of the earth that shows daylight and night zones, the local weather conditions for places you have selected to display, and optionally a cloud layer with current satellite cloud data. You can set up alarms for the local time of any city.
