Simple Timetracker is an application useful for keeping a record of time spent on projects and activities therein. You use mouse-drag gestures to 'paint' time spent on a task on a continuous timeline. It takes care to make sure any particular stretch of time is attributed to at most one task. It records data, via JDBC, in a database. By default, it uses HSQLDB, but (for example) a PostgreSQL database on a central server may be used.
