good time tracking software, i.e. keeping track of work tasks that I work on...

[Walter Tautz <wtautz@math.uwaterloo.ca>]

i'm currently using titrax but it seems a little simplistic...

If possible I'd like something that could track keystrokes perhaps....detect
idleness.....needless to say this is just for my own use, I'm not tracking
anyone else :-)
