Timetracker is a Java application for recording time spent on projects and activities. We've been using Timetracker at LShift for a few years.
The latest version is 1.1.4, which has a bunch of improvements and bugfixes over the last public release, version 1.1.
You can download either the binaries or the source.
Unzip your chosen distribution. In the resulting directory there's a README, which tells you how to install, configure and/or build it.
This software has been developed with assistance from LShift Ltd.
