The Addition method defines the addition operator for TimeSpan values. It enables code such as the following:

TimeSpan time1 = new TimeSpan(1, 0, 0, 0);   // TimeSpan equivalent to 1 day.
TimeSpan time2 = new TimeSpan(12, 0, 0);     // TimeSpan equivalent to 1/2 day.
TimeSpan time3 = time1 + time2;              // Add the two time spans.

Console.WriteLine("  {0,12}\n +  {1,10}\n   {3}\n    {2,10}", 
                  time1, time2, time3, new String('_', 10));
// The example displays the following output: 
//           1.00:00:00 
//        +    12:00:00 
//          __________ 
//           1.12:00:00

Languages that do not support custom operators can call the Add method instead.
