title: MomentJS - convert datetime from UTC to different timezone
body: <p>I am trygin to convert utc time to local timezone with moment but without success.. Here is my code:</p>
  
  <pre><code>var utc = moment.tz('2017-03-28 15:00:00','UTC');
  var s = utc.format();
  var pl = moment.tz(utc.format(), 'Europe/Warsaw').format();
  console.info(s);
  console.info(pl);
  </code></pre>
  
  <p>and the output is:</p>
  
  <pre><code>VM4496:4 2017-03-28T15:00:00Z
  VM4496:5 2017-03-28T17:00:00+02:00
  </code></pre>
  
  <p>As you can see, moment adds 2 hours to UTC, but <code>Europe/Warsaw</code> is in <code>UTC+1</code> time zone</p>
