title: How to Include moment-timezone in Angular 2 App
body: <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>
