    Implementation of the date and time profiles specified in XEP-0082 using Python's
    datetime module. The legacy format described in XEP-0082 section "4. Migration" is not
    supported. Reexports of the functions in :mod:`sat.tools.xmpp_datetime`.

    This is a passive plugin, i.e. it doesn't hook into any triggers to process stanzas
    actively, but offers API for other plugins to use.
