Whenever the Military Time button is pushed the Military time is displayed, but only for one second. It then reverts back to standard 12 hour digital time. What is going on, and can anyone help me to fix this?

The action performed is at the bottom of the code, and the time is in the run() not the init().
You will probably need to push the button a couple of time to actually see the digital time go into Military time.
Also the applet window will need to be extended to actually see the button.
Please excuse some of my code and the way it is formatted. Thank you for you time and help.
