How to configure JSpinner to accept number of hours (with mins and secs)

Question

I'm having a problem trying to figure out a simple way to enable a JSpinner to do allow the input in this format:
n hours : n minutes : n seconds
ex: 100 : 0 : 0, 1:59:59, 25:30:00
Where n hours could be from 0-n (not restricted by 24 hours) and minutes and seconds are, of course, < 60. That is, I can enter number of hours, not a date, or a specific time in a day.
I'm thinking the only way to do this is with a custom spinner model and custom editor? Or is there a simple way I can make the date model in spinner to allow me to do this?
Thanks

import java.awt.*;
import javax.swing.*;
import java.util.*;
public class Test2 extends JFrame {
  public Test2() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Container content = getContentPane();
    content.setLayout(new FlowLayout());
    content.add(new MySpinner());
    setSize(300, 300);
    setVisible(true);
  public static void main(String args[]) { new Test2(); }
class MySpinner extends JSpinner {
  public MySpinner() {
    setModel(new SpinnerDateModel(
      new GregorianCalendar(2004,0,1,0,0,0).getTime(),
      null, null, Calendar.DAY_OF_YEAR));
    setEditor(new DateEditor(this,"HH:mm:ss"));
