SDATimer for Windows

This handy program displays the date and time and improves on the standard Windows clock utility with a stopwatch and countdown timer.

SDA Timer's interface is a bit plain but is very easy to use, and you can choose from several skins for the clock display. The countdown timer, calendar, and stopwatch are easily accessible from the context menu or by using hot keys.

The simple but effective tools are set up primarily with novice-friendly radio buttons and pull-down menus. You can easily add a WAV file or user-created text alerts to the countdown timer, or opt to run a program or shut down the computer when the timer reaches zero.

SDA Timer doesn't have the most polished design, but it's a fine choice if you just want a simple way to track time on the computer.
