func chilkatTest() {
    let dateTime = CkoDateTime()

    dateTime.SetFromCurrentSystemTime()

    print("Current time: \(dateTime.GetAsTimestamp(false))")

    dateTime.AddSeconds(1)
    print("Current time + 1 second: \(dateTime.GetAsTimestamp(false))")

    dateTime.AddSeconds(-2)
    print("Current time - 1 second: \(dateTime.GetAsTimestamp(false))")

    // Add 30 days (60 * 60 * 24 * 30)
    dateTime.AddSeconds(60 * 60 * 24 * 30)
    print("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
