Finally, I added the last option needed to call TimeTracker a 1.0 release. You now can pass the time of stop and start of a task. Unfortunately, there isn’t a way to change the time of a task that has already been stopped or started; maybe on 1.1? :)
Anyway, TimeTracker 1.0RC1 “Are we there yet? Are we there yet? Are we there yet?” is available at TimeTracker homepage.
