Javascript timezone conversion displays NaN in Internet Explorer

Question

I am using the following javascript to convert UTC times into the users local timezone...

(function() {
  (function($) {
    return $.fn.localtime = function() {
      var fmtDate, fmtZero;
      fmtZero = function(str) {
        return ('0' + str).slice(-2);
      };
      fmtDate = function(d) {
        var hour, meridiem;
        hour = d.getHours();
        if (hour < 12) {
          meridiem = "AM";
        } else {
          meridiem = "PM";
        }
        if (hour === 0) { hour = 12; }
        if (hour > 12) { hour = hour - 12; }
        return hour + ":" + fmtZero(d.getMinutes()) + " " + meridiem + " " 
      };
      return this.each(function() {
        var tagText;
        tagText = $(this).html();
        $(this).html(fmtDate(new Date(tagText)));
        return $(this).attr("title", tagText);
      });
    };
  })(jQuery);
    }).call(this);

This all works fine in every browser apart from Internet Explorer, instead of converting the time it just displays 'NaN'

Can anyone see why this is happening?

What do the original dates in the HTML look like? Browsers differ in the variety of dates that they can parse with `new Date(...)`. — Barmar, Feb 07 '13 at 11:17
The original dates are in this format '2012-02-07T13:30:00Z' — fightstarr20, Feb 07 '13 at 11:23
Internet Explorer does not support that (standardized) Date format in older versions and in Quirks mode, you will need to parse it manually. — Bergi, Feb 07 '13 at 11:33
