How to Include moment-timezone in Angular 2 App
<p>I realize, this question is repeated but previous once does not provide apt answer 
moment package was already installed</p>

<p><strong>1.Installed package<br></strong> </p>

<p><strong>npm install moment-timezone --save</strong></p>

<p>Inside <strong>node_modules</strong> directory
<br>
|<br>
|--moment<br>
|--moment-timezone</p>

<p>directories present</p>

<p><strong>2.</strong>
<strong>Index.html</strong> included script</p>

<pre><code>&lt;script src="node_modules/moment-timezone/moment-timezone.js"&gt;&lt;/script&gt;
</code></pre>

<p><strong>System.config.js</strong></p>

<pre><code>  var map = {
    'moment':             'node_modules/moment',
    'momentzone':         'node_modules/moment-timezone'
  };
  var packages = {
    'moment':             { defaultExtension: 'js' },
    'momentzone':         { defaultExtension: 'js' }
  };
</code></pre>

<p><strong>3.Inside component.ts file</strong></p>

<pre><code>import * as moment from 'moment/moment';

export class TimeComponent implements OnInit{
   ngOninit(){
         console.log(moment("2014-06-01T12:00:00Z").tz('America/Los_Angeles').format('ha z'));

   }
}
</code></pre>

<p>What should be imported to prevent error
<strong>Property tz does not exist on type 'Moment'</strong></p>
