Hot Spot Question - Timestamp of Clicks

Hi, Does anyone know how to capture the timestamps of user clicks on a question? My specific issue is that I have various clickable regions setup in a Hot Spot question, and I'd like to collect information on the order of items clicked (given multiple can be clicked). I assume the best way to get at that would be to record the timestamp of the clicks, but timestamp alone doesn't tell you which region was clicked at what time. Any suggestions as to how to do something like this, or any other ways to solve my problem would be greatly appreciated. Thanks for your help!
