title: How to properly place Date in <pubdate> element on RSS feed
body: <p>I'm using RSS Graffitty to post RSS items to a facebook page.</p>
  
  <p>The app told me the items were missing the publication date so I added this tag:</p>
  
  <pre><code>echo "&lt;pubdate&gt;".$row['Date']."&lt;/pubdate&gt;";
  </code></pre>
  
  <p>$row['Date'] is obtained from my MySQL database and it's a Datetime column.</p>
  
  <p>How must I format it/echo it so it's recognized by the RSS feed? Must I change the element?</p>
  
  <p>Thanks</p>
