title: Json Stringify date produces a wrong date compared to javascript date
body: <p>When i create a <code>javascript</code> date and then <code>stringify</code> it and send it to the server, i get two different dates. The <code>stringified</code> date is always one day behind.</p>
  
  <p>So currently i increment my <code>javascript</code> date by 1 day so that i receive the same date on the server.</p>
  
  <p>my current code:</p>
  
  <pre><code>var dt = $(.datepicker).datepicker('getDate');//Fri Aug 26 2016 00:00:00 GMT+0200 (South Africa Standard Time)
  var result = Json.stringify(dt); //"2016-08-25T22:00:00.000Z"
  </code></pre>
  
  <p>Is this the correct approach or am i missing something?</p>
