Banning for an amount of time

Hey,

quick question:

Openfire has an option to ban for an amount of time, is there a way a client using bosh can send a package

to openfire specifying to ban someone for an amount of time or are there any plugins to do this ?

Ive read this: http://xmpp.org/extensions/xep-0045.html#ban, but im not finding anything.

thx in advance,

azul
