Problem with Javascript Date function in IE 7, returns NaN

Question

I have a twitter feed and I create a new date obj so I can format the date to my liking.

var created = new Date(this.created_at) works in firefox and c

You'll want to make sure the date is parsed as UTC, because otherwise javascript will interpret it as a date in your local timezone.

The date looks like this: Tue Jul 13 23:18:36 +0000 2010

You can parse it like this:

function parseDate(str) {
  var v=str.split(' ');
  return new Date(Date.parse(v[1]+" "+v[2]+", "+v[5]+" "+v[3]+" UTC"));
} 

Which will give the correct date/time in the local timezone, for example: Tue Jul 13 2010 19:18:36 GMT-0400 (EDT)

So that should leave your code looking something like this:

$(function(){
  $.getJSON("http://twitter.com/statuses/user_timeline/google.json?count=1&callback=?", function(data){
    $.each(data, function(){
      var created = parseDate(this.created_at);
      $("
").append("
Unformatted: " + this.created_at + "
Formatted: " + created + "
").appendTo("body");
    });
  });
  function parseDate(str) {
    var v=str.split(' ');
    return new Date(Date.parse(v[1]+" "+v[2]+", "+v[5]+" "+v[3]+" UTC"));
  } 
});
