Tracking where your time goes

Many of us waste time by getting distracted (e-mails, browsing etc.)
I use this cool software called TimeLeft to keep track of time. The free app can be downloaed from:

This is a very powerful program. I use the countdown and stopwatch feature to restrict spending my time on non-productive tasks.

If you know of any other productivity enhancing tool, please share.
