title: jQuery live clock with optional 24 or 12 hours
body: <p>How do you make a jQuery <b>only</b> live clock that automatically loads and starts moving, with this structure?:</p>
  
  <p>hour:minute:second</p>
  
  <p>Two columns each separated by semicolons, and also have a universal or not option (e.i. 6'o'clock vs. 18'o'clock). It would have a button next to it that would toggle back and forth saying "change display" or something  </p>
