    XEP-0203: Delayed Delivery

    XMPP stanzas are sometimes withheld for delivery due to the recipient
    being offline, or are resent in order to establish recent history as
    is the case with MUCS. In any case, it is important to know when the
    stanza was originally sent, not just when it was last received.

    Also see <http://www.xmpp.org/extensions/xep-0203.html>.
