A simple Time Tracker using QT, similar to KTimeTracker for KDE4. It even uses the same file format so that You can view the old data. Plus it does not depend on the whole KDE Frameworks thing, so that could be a plus for somebody.
So far, lot of features from KTimeTracker are missing, the most important would be activity detection, idle detection and running in the system tray.
Debian/Ubuntu:
dpkg-buildpackage
sudo dpkg -i ../qttrack*.deb
Other:
qmake .
make
sudo make install
