WorldClock

WorldClock is the definitive desktop clock program for Windows. It offers timezone, timesync, alarm, reminder and calendar functionality as well as giving you the option of enhancing your desktop wallpaper with time and weather related information. Please refer to the Description section (click on the 'Description' link in the navigation bar on the left) for a detailed description of WorldClock's features and operation.

You can download a trial version of WorldClock by clicking on the download link. Note that the trial version of WorldClock is fully functional but has the following constraints:

  • It does not save application settings between sessions (the registered version obviously will).
  • Although the TimeSync function operates normally and will tell you how much your PC's clock is off, it will not reset the clock (again, the registered version will).

If you're a registered user, go to the What's New section for a list of the latest changes and news.

Here's a screenshot of the WorldClock main screen under Windows XP:

WorldClock is fully compatible with Windows 2000, Windows 2003, Windows XP, Windows Vista, Windows 7, and Windows 8/8.1 (both 32-bit and 64-bit versions).
