I installed ktimetracker from Sofware Center. When I run it trough launcher o writing "ktimetracker" in console. It ask me for a iCalendar file (I think so), I've never heard of that type of file, so, I create a empty file with the extension .ics (I think this is the extension of iCalendar files) and I specified ktimetracker that use that file, but it doesn't work. Some one knows what I have to do to get ktimetracker work?
