title: How can I calculate the time between 2 Dates in typescript
body: <p>This works in Javascript</p>
  <pre><code>new Date() - new Date(&quot;2013-02-20T12:01:04.753Z&quot;)
  </code></pre>
  <p>But in typescript I can't rest two new Dates</p>
  <pre><code>Date(&quot;2013-02-20T12:01:04.753Z&quot;)
  </code></pre>
  <p>Don't work because paremater not match date signature</p>
