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
