Well now, setting the clock on a Windows PC using the JVM and setting the clock using the JVM on the computer chip in your palmPilot would be slightly different don't you think?
Quite operating system specific.

Here's the only way I know to make the clock show up in the frame border... use a thread to update the label on the frame... hopefully this is what you wanted...

import java.awt.*;
import java.awt.event.*;
import java.util.Date;
import java.text.SimpleDateFormat;
 
public class TimeFrame extends Frame implements Runnable
{
    Thread timeThread;
    boolean threadOn;
 
    public TimeFrame()
    {
        super();
    }
 
    public void start()
    {
        timeThread = new Thread( this );
        threadOn = true;
        timeThread.start();
    }
 
    public void stop()
    {
        threadOn = false;
    }
 
    public void run()
    {
        long time = System.currentTimeMillis();
        long delay = 1000;
        SimpleDateFormat formatter =
            new SimpleDateFormat( "hh:mm:ss a" );
 
        while( threadOn )
        {
            time += delay;
 
            try
            {
                Thread.sleep( Math.max( 0,
                    time - System.currentTimeMillis() ) );
            }
            catch( InterruptedException x )
            {
                System.err.println( "Thread interrupted!!!" );
            }
 
            String date = formatter.format( new Date() );
            setTitle( date );
        }
    }
 
    public static void main( String[] args )
    {
        final TimeFrame tf = new TimeFrame();
        tf.setSize( 200, 200 );
        tf.start();
 
        tf.addWindowListener( new WindowAdapter(){
            public void windowClosing( WindowEvent e )
            {
                tf.stop();
                tf.setVisible( false );
                System.exit( 0 );
            }
        } );
 
        tf.setVisible( true );
    }
}
