title: Moment js format date with timezone
body: <p>Hi I am using Ember+moment.js to format date in my ember helpers.</p>
  
  <p>I am getting the following date from the service </p>
  
  <p><strong>Tue Aug 23 2016 09:43:53 GMT+0200 (W. Europe Daylight Time)</strong></p>
  
  <p>In my ember helper class i am able to format date using following code :</p>
  
  <pre><code>var formattedDate = moment(date).format('DD/MM/YYYY h:mm a');
  </code></pre>
  
  <p>I am getting the following output :</p>
  
  <p><strong>23/08/2016 9:43 am</strong></p>
  
  <p>Expected Output : <strong>23/08/2016 9:43 am GMT</strong></p>
  
  <p>How can i specify the timezone flag in the format function?</p>
  
  <p>Any help should be appreciated.</p>
