Django DateTimeField ValidationError: value has an invalid format
<p>I'm getting a validation error when trying to store a date time in a django DateTimeField. </p>

<p>The format I'm trying to save is below, together with the error. :</p>

<pre><code>django.core.exceptions.ValidationError: ["'Mon, 23 May 2016 08:30:15 GMT' value has an invalid format. It must be in YYYY-MM-DD HH:MM[:ss[.uuuuuu]][T
</code></pre>

<p>In my django settings I have:</p>

<pre><code>DATE_INPUT_FORMATS = ("%d %b %Y", )
</code></pre>

<p>Should I be converting the format before saving or can I add to <code>DATE_INPUT_FORMATS</code> </p>
