timeclockj is a tool used for time-tracking your activities, enabling syncronisation between desktop and mobile devices by using Dropbox.

The desktop application is written in Java and sits in the System Tray (Task Bar) of the host operating system.

See the Android version online here, with built-in Dropbox support enabling users to sync between desktop and Linux, Mac or Windows.
