title: Momentjs return wrong date after minutes manipulation
body: <p>In my php application I set the italian timezone like this way:</p>
  
  <pre><code>date_default_timezone_set('Europe/Rome');
  </code></pre>
  
  <p>the string above is located in my <code>config.php</code> file, the core of the app. Anyway, from the backend I using <code>momentjs</code> with <code>CodeIgniter</code> framework. When a user select a date from the properly input set this result:</p>
  
  <p><a href="https://i.stack.imgur.com/qYX0F.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qYX0F.png" alt="enter image description here"></a></p>
  
  <p>Now I get the value from this input like this:</p>
  
  <pre><code>var end_date_temp = Date.parse($('#end-datetime').val());
  </code></pre>
  
  <p>And the initial result is wrong:</p>
  
  <blockquote>
    <p>Tue Mar 01 2016 11:03:00 GMT+0100 (ora solare Europa occidentale)</p>
  </blockquote>
  
  <p>The rest of code is:</p>
  
  <pre><code>var end_date = moment(end_date_temp).add(serviceDuration, 'minutes').format('DD/MM/YYYY HH:mm');
  $('#end-datetime').val(end_date);
  </code></pre>
  
  <p>NB: I also tried to set <code>moment.locale('it')</code> but the same result appear, in my javascript libraries I've the italian timezone of momentjs. What is wrong? </p>
  
  <p>UPDATE Code:</p>
  
  <pre><code>var end_date_temp = moment($('#end-datetime').val())._i;
  var end_date = moment(moment(end_date_temp).add(serviceDuration, 'minutes')).format('DD/MM/YYYY HH:mm');
  $('#end-datetime').val(end_date);
  </code></pre>
