Parsing a date in long format from ATOM feed

Question

I get this date in javascript from an rss-feed (atom):

2009-09-02T07:35:00+00:00

If I try Date.parse on it, I get NaN.

How can I parse

Answer 1

Here is my code, with test cases:

function myDateParser(datestr) {
var yy   = datestr.substring(0,4);
var mo   = datestr.substring(5,7);
var dd   = datestr.substring(8,10);
var hh   = datestr.substring(11,13);
var mi   = datestr.substring(14,16);
var ss   = datestr.substring(17,19);
var tzs  = datestr.substring(19,20);
var tzhh = datestr.substring(20,22);
var tzmi = datestr.substring(23,25);
var myutc = Date.UTC(yy-0,mo-1,dd-0,hh-0,mi-0,ss-0);
var tzos = (tzs+(tzhh * 60 + tzmi * 1)) * 60000;
return new Date(myutc-tzos);
}


javascript:alert(myDateParser("2009-09-02T07:35:00+00:00"))
javascript:alert(myDateParser("2009-09-02T07:35:00-04:00"))
javascript:alert(myDateParser("2009-12-25T18:08:20-05:00"))
javascript:alert(myDateParser("2010-03-17T22:30:00+10:30").toGMTString())
