    var day = hour = min = "";
    if (second>86400) {
      day = Math.floor (second/86400) + "days";
      second = second%86400;
    }
    if (second>3600) {
      hour = Math.floor (second/3600) + "when";
      second = second%3600;
    }
    if (second>60) {
      min = Math.floor (second/60) + "min";
      second = second%60;
    }
    Second = second+ "seconds";
    return day+hour+min+second;
  }
  var Timeele = document.getElementById ("Expiretime");
  var timer = Window.setinterval (function () {
    timeele.innerhtml = Expiretime (expire--);
    if (expire<0) {
      clearinterval (timer);
