title: How to get Timezone offset from moment Object?
body: <p>I have <code>moment</code> Object defined as:</p>
  
  <pre><code>var moment = require('moment');
  
  moment('2015-12-20T12:00:00+02:00');
  </code></pre>
  
  <p>When I print it, I get:</p>
  
  <pre><code>_d: Sun Dec 20 2015 12:00:00 GMT+0200 (EET)
  _f: "YYYY-MM-DDTHH:mm:ssZ"
  _i: "2015-12-20T12:00:00+02:00"
  _isAMomentObject: true
  _isUTC: false
  _locale: r
  _pf: Object
  _tzm: 120
  </code></pre>
  
  <p>How to fetch by right way <code>_tzm</code>? (suppose its offset in minutes)</p>
  
  <p>Thanks,</p>
