title: Extracting utcOffset from an ISO String with Moment.js
body: <p>Using moment.js, I'm attempting to extract the offset from an ISO date string so I can use the offset later when formatting an epoch timestamp to ensure the conversion of the timestamp is in the same timezone.</p>
  
  <p>Even though the offset in the string is -0400, the result is always 0;</p>
  
  <pre><code>var currentTime = "2015-03-18T16:10:00.001-0400";
  var utcOffset = moment(currentTime).utcOffset(); // 0
  </code></pre>
  
  <p>I've attempted to use parseZone() as well without success.  Is there a way to extract -0400 from the string so I can use it while formatting another time?</p>
  
  <p>Thanks for the help!
