JavaScript Countdown Timer to specific time everyday

Question

I am currently developing a website with a countdown timer at the headline: http://iphone.myhandykey.com/

The current timer is just 12hrs + few mins.. What I would like

Answer 1

(function() {
  var start = new Date;
  start.setHours(23, 0, 0); // 11pm

  function pad(num) {
    return ("0" + parseInt(num)).substr(-2);
  }

  function tick() {
    var now = new Date;
    if (now > start) { // too late, go to tomorrow
      start.setDate(start.getDate() + 1);
    }
    var remain = ((start - now) / 1000);
    var hh = pad((remain / 60 / 60) % 60);
    var mm = pad((remain / 60) % 60);
    var ss = pad(remain % 60);
    document.getElementById('time').innerHTML =
      hh + ":" + mm + ":" + ss;
    setTimeout(tick, 1000);
  }

  document.addEventListener('DOMContentLoaded', tick);
})();

Only  left!
