Adding Timer variation

Curious to know if anyone has created a timer to track the amount of time spent on a quiz?  I want to develop a navigation quiz and have learners try to beat a top score time.  Of course, the shorter the time, the better.  When they are finished with the quiz, it stops the clock and tells them their time.  This score would then be posted to a Best Time page and rank the times shortest to longest.
