title: Get Milliseconds from Ticks in DateTime c#
body: <p>I have a simple DateTime object, equal to the date: <code>11/1/2020 8:11:14 AM</code>.</p>
  <p>I want to convert it to milliseconds so I do:
  <code>myTimestamp?.Ticks / TimeSpan.TicksPerMillisecond</code>.</p>
  <p>I get <code>63739786274788</code>, which seems correct from the pure calculation perspective.</p>
  <p>However, when I input it into one of the <a href="https://currentmillis.com/" rel="nofollow noreferrer">online converters</a> to validate, I get the date <code>Wed Nov 01 3989 01:11:14</code>, which is of course way off.</p>
  <p>Questions:</p>
  <ol>
  <li>What is this number <code>63739786274788</code> if not time in ms?</li>
  <li>How do I get &quot;normal&quot; timestamp in ms?</li>
  </ol>
