Makes tracking and logging time easy for JIRA users.
Click the clock to start tracking your time. When you want to stop just go to whatever ticket you want to log that time against and click the clock again.
It fills out the time for you!
It can even log work against tickets selected in your agile/greenhopper boards.
No authentication necessary and no special permissions needed.
