Elapsed Time: General-Purpose Classes

|  Overview |  How Do I

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.
