Timesheet
Automatically logs working times according to wifi or computer uptime
...This way, you can either lock your screen manually when taking breaks or configure your screensaver to lock the screen after n minutes, so it will automatically log your breaks.
After a week or a month you can export your worksheet in .txt format. Simply give a timespan and hit "export" to generate the file.
Timesheet will start hidden. You can access the settings and export by double-clicking the tray icon.
System date format has to be either dd.mm.yyyy or dd/mm/yyyy
