GnoTime: A Marvelously Manic Time Tracker
If your work routine at all resembles mine, you probably have little or no time to squeeze in new appointments or run unscheduled errands. That is where the GnoTime Tracking Tool can save your work day and probably much of your night time as well.
The Gnome Time Tracker comes close to doing it all. It works as your to-do list. It can serve as your diary or work journal. Even better, it can track how much time you spend on projects. If those functions do not qualify GnoTime as the Linux killer app of the year, then maybe its ability to generate reports and invoices based on that time log will.
When it comes to tracking what I do and when, I have yet to find a Linux app that measures up to the productivity I get from GnoTime.
