Can't set Carbon date to null in Laravel 5
<p>I have a column <code>dateTime</code> in my migrations that Laravel assumes as <code>Carbon</code>. The column name is <code>terminado_em</code> and is nullable.</p>

<p>I have setted a <code>Carbon</code> value using my model.</p>

<p>Now when I want to set <code>terminado_em</code> to <code>null</code>:</p>

<pre><code>public function reiniciar()
{
    $this-&gt;terminado_em = null;
    ...
}
</code></pre>

<p>I get the error</p>

<pre><code>InvalidArgumentException in Carbon.php line 425: Data missing
</code></pre>

<p>How to set a <code>Carbon</code> property to null when it's already set to a <code>Carbon</code> value?</p>
