title: how to make Carbon null in laravel?
body: <p>I'm making a table in Laravel and I want my &quot;besttime&quot; to be a <code>nullable</code> but it's returning the current time if I keep it empty.
  (I'm using carbon because I want the <code>H:i</code> format without the seconds)
  here's what my input looks like</p>
  <pre><code>@foreach ($records as $record)
      &lt;tr&gt;
          &lt;td&gt;{{ Carbon\Carbon::parse($record-&gt;besttime)-&gt;format('H:i') }}&lt;/td&gt;
      &lt;/tr&gt;
  @endforeach
  </code></pre>
