    dt.SetFromCurrentSystemTime();
    System.out.println("Now: " + dt.getAsTimestamp(true));

    //  Add 10 minutes, making the date 10 minutes in the future.
    dt.AddSeconds(600);
    System.out.println("10 minutes from now: " + dt.getAsTimestamp(true));

    //  Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?
    boolean b = dt.ExpiresWithin(10,"seconds");
    System.out.println("Expires within 10 seconds: " + b);

    //  Does the date/time expire within 5 minutes?
    b = dt.ExpiresWithin(5,"minutes");
    System.out.println("Expires within 5 minutes: " + b);

    //  Does the date/time expire within 15 minutes?
    b = dt.ExpiresWithin(15,"minutes");
    System.out.println("Expires within 15 minutes: " + b);

    //  Does the date/time expire within 1 hour?
    b = dt.ExpiresWithin(1,"hour");
    System.out.println("Expires within 1 hour: " + b);

    //  Does the date/time expire within 1 day?
    b = dt.ExpiresWithin(1,"day");
    System.out.println("Expires within 1 day: " + b);

    //  Output:

    //  	Now: 2017-05-05T23:48:00-0500
    //  	10 minutes from now: 2017-05-05T23:58:00-0500
    //  	Expires within 10 seconds: False
    //  	Expires within 5 minutes: False
    //  	Expires within 15 minutes: True
    //  	Expires within 1 hour: True
    //  	Expires within 1 day: True
