Workers who travel, or who work at companies with locations around the world, this clock is for you. I often find myself checking the time on the west coast before picking up the phone, and find myself either adding three hours to the current time or looking up a list of time zones when I don't have the time difference memorized, and when I travel if I don't set my watch when the plane lands and the pilot announces the local time, I'm out of whack for hours. This World Time Clock from the New York Museum of Modern Art (MoMA) is an elegant gadget that will help you with your time zone woes.

The clock has completely unmarked numbers on the front, and uses rotational symmetry to keep the displayed time accurate to the time zone on the top of the clock. So if you're looking for the time in, say, New York, just roll the clock over so the side that's etched with "New York" is showing on top and you'll have the accurate time for that time zone. Headed to London? Roll the clock over a little, and there you go. For whichever city is displayed at the top, you have the correct time, and it includes all 24 of the global time zones. The clock is portable, too - only about 3.5 inches long and 2 inches wide, making it easy to drop in your carry-on when you get on the plane. You can order one online for $74.00 from the MoMA Store. MoMA members get a discount and can pick one up for $66.00. [via ShinyShiny]
