A Date.parse implementation from Stackoverflow stuffs.

date-dot-parse.js

// This is a slightly modified version of two patches. The first suggested at
// http://stackoverflow.com/questions/5802461/javascript-which-browsers-support-parsing-of-iso-8601-date-string-with-date-par
// and the second, for Date.js suggested at
// http://stackoverflow.com/questions/12145437/date-js-parsing-an-iso-8601-utc-date-incorrectly
//
// Here we override the implementation of Date.parse provided by Date.js. In this implementation we
// first check to see if we can construct the date using the Date constructor. If we can, we move
// along. If we cannot, we attempt to start the Date.js grammar parser. If that, too, fails us, we
// then assume we're running in IE 8, and someone passed in an ISO8601 string, which IE8's date
// constructor won't recognize. So we try to manually parse it out, returning a Date instance.
//

Date.parse = function (dateString) {
  var date, time, r = null;
  if (! dateString)
    return null;

  if (dateString instanceof Date)
    return dateString;

  date = new Date(Date._parse(dateString));
  time = date.getTime();

  // The following will be FALSE if time is NaN which happens if date is an Invalid Date 
  // (yes, invalid dates are still date objects. Go figure.)
  if (time === time)
    return date;

  // try our grammar parser
  try {
    r = Date.Grammar.start.call({}, dateString.replace(/^\s*(\S*(\s+\S+)*)\s*$/, "$1"));
  } catch (e) {
    return null;
  }
  var grammarParserResult = ((r[1].length === 0) ? r[0] : null);

  if (grammarParserResult !== null)
    return grammarParserResult;

  // The Grammar parser and date constructor failed. That means we were passed an
  // ISO 8601 string that doesn't compute using the date constructor likely because
  // we're in freaking IE 8. Our last ditch effort is to try and parse the 8601 date
  // manually.
  var parts = dateString.match(/\d+/g);
  var isoTime = Date.UTC(parts[0], parts[1] - 1, parts[2], parts[3], parts[4], parts[5]);
  var isoDate = new Date(isoTime);

  return isoDate;
};
