TimeIT is a time tracker that works quietly almost without any interaction and still measures the time you are spending on several projects. The concept of this program is that tasks and projects are assigned to workspaces and while you are in those workspaces your projects are timed. It also has detection of idleness, editing of time records, and summary views grouped by day, week, month, and year.
Thanks Tinkster. I have now added a tar.gz with configure present as default downlad. (pending approval as of writing)
