Ever wish you had a really quick way of figuring out what time it is somewhere else in the world? I was recently on gadling.com and learned about a site called TimeZoneCheck which allows you to do just that.
You enter in a city, it shows up on a map, and when you fly over it with your cursor you get the time at that destination. It's not a perfect interface, but it'll do. I was especially distraught when I discovered that my hometown of St. Louis was not included. But then I typed in "Saint Louis," and it appeared. Whew.
Check it out. And next time I'm traveling and you're dying to know if I'm awake or sound asleep, you'll be able to make an educated guess.
