The World Time Engine is a surprisingly robust site that goes much further than just telling you what time it is in Beijing or Calcutta right now. The site allows you to compare the time in up to 5 different places and comes with a meeting planner that helps you figure out what the best time for a conference call would be between people scattered all over the globe. To get started, simply enter any country, city, town, street, zip code, or geo coordinates into the search box and then click on “Get Time”. Search more than one location using “and” between terms. Finally, they’ve even included a Talking World Clock which you can access from anywhere by picking up the phone.
