title: Moment Timezone in Angular 9
body: <p>Currently, I upgrade my Angular project form <code>8</code> to <code>9</code>. <br>
  The project's using a <code>&quot;@types/moment-timezone&quot;: &quot;^0.5.30&quot;</code> in <code>package.json</code> <br>
  Now this package has been deprecated. <a href="https://www.npmjs.com/package/@types/moment-timezone" rel="nofollow noreferrer">https://www.npmjs.com/package/@types/moment-timezone</a> <br></p>
  <p>When I run the project <code>ng serve</code>, it shows up this error message</p>
  <pre><code>user.model.ts:3:25 - error TS7016: Could not find a declaration file for module 'moment-timezone'. '/home/bunthai/sftp/upgrade/projectg/ui/ctr/node_modules/moment-timezone/index.js' implicitly has an 'any' type.
    Try `npm install @types/moment-timezone` if it exists or add a new declaration (.d.ts) file containing `declare module 'moment-timezone';`
  
  import * as moment from 'moment-timezone';
                            ~~~~~~~~~~~~~~~~~
  </code></pre>
  <p>How to deal with this problem? <br></p>
