Hi,
To calculate the elapsed time between two events, you need to save the start time using time.clock(). Once the event has ended take the current time using time.clock() again, and subtract the start time. This will give you the correct elapsed time. Here's some sample code:
Code:
#Save start of event
startTime = time.clock()
.
.
.
#Calculate elapsed time
elapsed = time.clock() - startTime
