I receive from a Webservice a String with a date in this format:

yyyy-MM-ddTHH:mm:ss.fffZ

I need to convert that String with JavaScript to a normal DateTime but without using the new Date('yyyy-MM-ddTHH:mm:ss.fffZ') because I'm using an old version of JavaScript that not support that conversion. I can split that string and get the:

Year

Month

Days

Time

but how to manipulate the time zone fffZ Any suggestions?

I've founded the solution. Please check http://webcloud.se/log/JavaScript-and-ISO-8601/

Date.prototype.setISO8601 = function (string) {

    var regexp = ([0-9]{4})(-([0-9]{2})(-([0-9]{2}) +

        (T([0-9]{2}):([0-9]{2})(:([0-9]{2})(.([0-9]+))?)? +

        (Z|(([-+])([0-9]{2}):([0-9]{2})))?)?)?)?;

    var d = string.match(new RegExp(regexp));



    var offset = 0;

    var date = new Date(d[1], 0, 1);



    if (d[3]) { date.setMonth(d[3] - 1); }

    if (d[5]) { date.setDate(d[5]); }

    if (d[7]) { date.setHours(d[7]); }

    if (d[8]) { date.setMinutes(d[8]); }

    if (d[10]) { date.setSeconds(d[10]); }

    if (d[12]) { date.setMilliseconds(Number(0. + d[12]) * 1000); }

    if (d[14]) {

        offset = (Number(d[16]) * 60) + Number(d[17]);

        offset *= ((d[15] == '-') ? 1 : -1);

    }



    offset -= date.getTimezoneOffset();

    time = (Number(date) + (offset * 60 * 1000));

    this.setTime(Number(time));

}
