How to get Timezone offset from moment Object? : <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>
