Stopwatch

StopWatch

This is a fairly intuitive class and uses the TimeStamp class under the hood for recording times.

Note that the stopwatch starts automatically, just use restart() if you wish to reset and start again.

   1 StopWatch stopwatch;
   2 TimeStamp time;
   3 time = stopwatch.split()
   4 cout << time << endl;
   5 time = stopwatch.elapsed()
   6 cout << time << endl;
   7 stopwatch.restart();
