Time tracker (web-based)?

[Ken D'Ambrosio]

Hey, all.  I know we have a fair number of contractors here, and I was 
wondering if anyone has a time tracker piece of software they 
particularly enjoy.  This is for my own personal use, so I'm just 
looking for straightforward: something to track time, what I did during 
that time, and (preferably) some sort of calendar interface to check it 
all out.

Any suggestions?

Thanks!
