Using the Stopwatch
The stopwatch measures elapsed time in units of 1/20 second up to
59 minutes, 59.95 seconds (60 minutes). When the maximum limit is
reached, the elapsed time returns to zero automatically and timing
continues from there.

The stopwatch is “reset” when all of
the three conditions exist.

operation not in progress
• Elapsed time measurement
operation not paused
