From the developer: "Travel Clock tells the time where you are, and where you want to be. You can set the alarm to go off at the same time each day. You can set or unset the alarm with a single tap. You have a snooze button if you need that extra couple of minutes of shut-eye. You can display the time where you are, and the time anywhere else on earth. The program has a database of over 400 locations around the world, and you can add as many more as you like. Daylight saving time is accounted for automatically, taking account of different rules in different countries. All data is backed up automatically when you hot-sync."
