title: datetimepicker getDate to return Date / Time in UTC format
body: <p>I happen to read this <a href="http://trentrichardson.com/examples/timepicker/" rel="nofollow noreferrer">datetimepicker</a> addon and found it to be of great use. The issue that I am facing using this tool is that I am unable to get data / time format in UTC or other formats (my intention is to at least get date / time in UTC format:</p>
  
  <pre><code>$('#starttime').datetimepicker({
      ampm: true,
      showHour: true,
      showMinute: true,
      showSecond: false,
      showMillisec: false,
      timeFormat: 'hh:mm TT',
      hourGrid: 4,
      stepHour: 1,
      minDate: minDate,
      maxDate: maxDate,
      stepMinute: 10
   });                             
  </code></pre>
  
  <p>The below script prints me data / time in below format:</p>
  
  <pre><code>var startDt = $('#starttime').datetimepicker('getDate');
  
  Tue May 01 2012 00:00:00 GMT+0530 (India Standard Time)
  </code></pre>
  
  <p>How can I change this format to any other like</p>
  
  <p>DD-MM-YYYY or DD/MM/YYYY or in UTC format?</p>
