Is there a Time Stamp in the Message?

Do you know whether the message protocol provide date Stamp in its message XML format?

Can't seem to find it specific in the Jabber doc, does that mean for message send, there will be no way to trace the sent date of the message?

Offline messages are stored (in the XML files on the HD) with the time stamp; it is then a feature of the client to show this information. Online messages do not have (obviously) the time stamp.
