Oregon Scientific's World Time Clock twists to tell you world time.

The handsome World Time Clock from Oregon Scientific is able to tell you the anytime in the world with just a simple twist. For instance if you needed to know what time it was in Paris, all you have to do is to turn the clock's brushed metal dial to select the city of Paris (it also has 11 other major cities) time zone, which will then show the current time underneath your local time on the inverted LCD display. The clock will automatically calculate and take daylight savings as well. It also comes with a basic alarm with snooze functionality.
