MinuteDock for Chrome is an extension for Google Chrome. A outstanding time tracking system, helping people who bill by the hour keep a handle on how long they're spending on each project. More information and free trial available at minutedock.com

This extension lets you start and stop your timer right from your browser toolbar, as well as lets you quickly see how much time you've got clocked up (and hopefully ready to bill!).

It also keeps track of how long you've spent "inactive" (not interacting with the browser for longer than X minutes) so you can adjust your entry accordingly (or not!).
