Test runner

var myArray = $("#original div")
myArray.sort(function(a, b) {
 a = parseInt($(a).attr("timestamp"), 10);
 b = parseInt($(b).attr("timestamp"), 10);
 if (a > b) {
  return 1;
 } else if (a < b) {
  return -1;
 } else {
  return 0;
 }
});
$("#original").append(myArray);

var myArray = $("#original div")
myArray.sort(function(a, b) {
 a = parseInt(a.getAttribute("timestamp"), 10);
 b = parseInt(b.getAttribute("timestamp"), 10);
 if (a > b) {
  return 1;
 } else if (a < b) {
  return -1;
 } else {
  return 0;
 }
});
$("#original").append(myArray);
