I'm using the Garmin Edge 500, and am looking to reconfigure my pages a bit for different applications. I see the field, "Time" listed with the definition of "Stopwatch Time." Is there some way that you can reset this time to 0:00 while riding? I'm wondering if it's possible to use this like an actual stopwatch to determine time gaps while racing.

If this is not possible, what's the difference between "Time" and "Time - Elpased," which they define as, "Total time recorded from pressing start to reset?"
