KTimeclock is designed to be a personal timeclock to keep track of how much time is spent working on various projects and the tasks that they involve. It evolved out of my own use of KArm and finding that although it was useful, there were many things that I would have done differently to make it easier to work with larger volumes of projects and tasks.
Simply set up a series of projects, each of which can contain multiple sub-projects and tasks. Select the current task that you're working on, start the clock, and KTimeclock will track the time you've spent working on that task.
If you have troubles getting KTimeclock to compile on your system, or have requests for other features or enhancements that you'd like to see in KTimeclock, please let me know.
