title: Timezone change in Moment timezone module
body: <p>I'm trying to set the timezone for Date string in NodeJS. The module for this is Moment Timezone.</p>
  
  <p>As from the docs:</p>
  
  <pre><code>var moment = require('moment-timezone');
  moment.tz.add('America/Los_Angeles|PST PDT|80 70|0101|1Lzm0 1zb0 Op0');
  
  var m = moment.tz("2013-11-18 11:55", "America/Los_Angeles");
  m.format();                     // 2013-11-18T11:55:00-08:00
  console.log(m);
  </code></pre>
  
  <p>But I've got the 2013-11-18T19:55:00.000Z.</p>
  
  <p>When I want to get something like 2013-11-18 11:55:00 GMT -0800. What's up? ;)</p>
