Deserialize javascript date on asp.net mvc 3 server

Question

I struggled with this problem for a while. I am trying to send an object to a client. After the client updates the object, I would like to send it back to the server and save it in my database. The first part works great. However, when I send it back, all dates are mixed up and start during the year 0001. I assume that since it cannot deserialize the date. Howe can I publish a json object with a date property and deserialize it to a type on a server with asp.net mvc 3?

Group

public class Group
{
    public Group();

    public string CreatedBy { get; set; }
    public DateTime CreatedOn { get; set; }
    public string Description { get; set; }
    public string Name{ get; set; }
    public string Status { get; set; }
    public string UpdatedBy { get; set; }
    public DateTime UpdatedOn { get; set; }
}

and

    public JsonResult updateGroup(Group group)
    {
        var result = Repository.updateGroup(group);
        return Json(result, JsonRequestBehavior.AllowGet);
    }

and on the client I received

    $.ajax({
        url: '../updateGroup',
        type: 'POST',
        data: JSON.stringify(group),
        dataType: 'json',
        contentType: 'application/json; charset=utf-8',
        success: function(){ success(); }
    });
