title: Strange DateTime format when returned from the Action in JSON type
body: <p>My Action: </p>
  
  <pre><code> public ActionResult Foo()
      {
          var date = DateTime.Now;
          return Json(date);
      }
  </code></pre>
  
  <p>and in the View I use post to visit the Action:</p>
  
  <pre><code>   $.post("../../Foo",function(data){
               alert(data);
     })
  </code></pre>
  
  <p>so strange the datetime truned to this format:</p>
  
  <pre><code>"/Date(1366340594875)/"
  </code></pre>
  
  <p>Anyone could tell me why? I want the date time what it is like "2013-1-1".</p>
