title: How can I customize date and time format in ngx-mat-datetime-picker?
body: <p>I am working on Angular7 and its compatible <strong>ngx-mat-datetime-picker</strong>. It works as expected.</p>
  <p>Want to customize the format:</p>
  <p><strong>Actual:</strong> <code>mm/dd/yyyy, hh:mm:ss</code>
  <strong>Expected:</strong> <code>yyyy-mm-dd hh:mm:ss</code></p>
  <p>Currently I don't find any option for formatting.</p>
  <p>I tried something like this in template <code>value=&quot;{{ mydate | date: 'yyyy-mm-dd hh:mm:ss' }}</code></p>
  <p>But not working.</p>
