title: Wrong month result using angularJS date filter
body: <p>I have this angularJS view that I want to render a date with this format: MMM YYYY
  My data is giving me the modified date as a string like &quot;20210410072612&quot;
  I have:</p>
  <pre><code>{{item.default['Date modified'].substr(4,2) | date:'MMM'}} {{item.default['Date modified'].substr(0,4)}}
  </code></pre>
  <p>The results from this are: <strong>Jan 2021</strong>
  The correct result should be <strong>Apr 2021</strong> since when I remove the date:'MMM' filter I got <strong>04 2021</strong> Any idea what I'm doing wrong?</p>
