Simple solution:

function ampmTo24(time)
{
  var hours = Number(time.match(/^(\d+)/)[1]);
  var minutes = Number(time.match(/:(\d+)/)[1]);
  var AP = time.match(/\s(.*)$/);
  if (!AP) AP = time.slice(-2);
  else AP=AP[1];
  if(AP == "PM" && hours<12) hours = hours+12;
  if(AP == "AM" && hours==12) hours = hours-12;
  var Hours24 = hours.toString();
  var Minutes24 = minutes.toString();
  if(hours<10) Hours24 = "0" + Hours24;
  if(minutes<10) Minutes24 = "0" + Minutes24;

  return Hours24 + ":" + Minutes24
}

But time.match for AP var does not works as there is no space between (07:30AM) time and am/pm – user13763 Apr 30 '14 at 09:05
