title: Include server time in XMPP message
body: <p>Is it possible to include to XMPP message time when message was delivered to server?</p>
  
  <p>Now I receive from OpenFire server messages like:</p>
  
  <pre><code>&lt;message id="W45Ky-21" to="eee@jserv.ee" from="ppp@jserv.ee/dfg5465fd" type="chat"&gt;&lt;body&gt;test&lt;/body&gt;&lt;/message&gt;
  </code></pre>
  
  <p>But I need know when message was sended (delivered to server) like:</p>
  
  <pre><code>&lt;message id="W45Ky-21" to="eee@jserv.ee" from="ppp@jserv.ee/dfg5465fd" type="chat"&gt;&lt;body&gt;test&lt;/body&gt;&lt;time&gt;2012-10-12 10:00:52&lt;/time&gt;&lt;/message&gt;
  </code></pre>
