(C#) DateTime - Add or Subtract Seconds
Demonstrates the AddSeconds method to add or subtract a number of seconds from a date/time.
Note: This example is only valid in Chilkat v9.5.0.65 or later.
Chilkat.CkDateTime dateTime = new Chilkat.CkDateTime();
dateTime.SetFromCurrentSystemTime();
Debug.WriteLine("Current time: " + dateTime.GetAsTimestamp(false));
dateTime.AddSeconds(1);
Debug.WriteLine("Current time + 1 second: " + dateTime.GetAsTimestamp(false));
dateTime.AddSeconds(-2);
Debug.WriteLine("Current time - 1 second: " + dateTime.GetAsTimestamp(false));
// Add 30 days (60 * 60 * 24 * 30)
dateTime.AddSeconds(60 * 60 * 24 * 30);
Debug.WriteLine("Current time + 30 days: " + dateTime.GetAsTimestamp(false));
// Sample output for test run on 2-Dec-2016:
// Current time: 2016-12-02T12:59:13Z
// Current time + 1 second: 2016-12-02T12:59:14Z
// Current time - 1 second: 2016-12-02T12:59:12Z
// Current time + 30 days: 2017-01-01T12:59:12Z
