title: Find out what time zone an RSS feed item was published
body: <p>I'm parsing an RSS 2.0 feed which has missing time zone information in its <code>pubDate</code> tag.</p>
  
  <p>For example, the element is written as such:</p>
  
  <pre><code>&lt;pubDate&gt;Tue, 3 Dec 2013 09:00:00&lt;/pubDate&gt;
  </code></pre>
  
  <p>How can I figure out or find out the time zone from this node element?</p>
