No timestamp in <x> element

I read in the spec that the jabber:x:delay element can have a timestamp element. Using smack to connect to a wildfire server I get back the following for offline messages.

Is there an api call that will tell the server to include the timestamp attribute?

Thanks in advance,

Adam

This is what I get for plain and chat messages:

What server and server version are you running against. If you running against Wildfire, do you have a particular configuration that forces the server to emit this information?

Thanks for your help.

I am using Wildfire 3.1 with no configuration that would affect timestamps.

What version of Smack are you using?
