The following procedure shows how to calculate the difference between two CTime objects and get a CTimeSpan result.

To calculate elapsed time

  • Use the CTime and CTimeSpan objects to calculate the elapsed time, as follows:

    CTime startTime = CTime::GetCurrentTime();

// ... perform time-consuming task ...

CTime endTime = CTime::GetCurrentTime();

CTimeSpan elapsedTime = endTime - startTime;

    Once you have calculated elapsedTime, you can use the member functions of CTimeSpan to extract the components of the elapsed-time value.
