how to get the server date time of a LIVE MESSAGE ?

I am not talking about delayed message. Delayed message can be got from stamp <delayxmlns='urn:xmpp:delay'
     from='capulet.com'
     stamp='2002-09-10T23:08:25Z'>
    Offline Storage
  </delay>

But how about a live message ? Does Openfire support that ?

The only information I see on the Internet is XEP-0131: Stanza Headers and Internet Metadata  However, Openfire does not support this XEP.

Please tell me how to resolve this. And I need server time because client time can be wrong. Thank you. Why such an obvious thing like this is not included in the message ....
