Well, currently GNUmed refreshes on any change to

        - the active patient
        - the waiting list table itself

as witnessed in this snippet:

        #--------------------------------------------------------
        def __register_events(self):
                gmDispatcher.connect(signal = u'waiting_list_generic_mod_db', 
receiver = self._on_waiting_list_modified)
                gmDispatcher.connect(signal = u'post_patient_selection', 
receiver = self._on_post_patient_selection)
        #--------------------------------------------------------

Oh, wait, the _on_post_patient_selection only does some of it:

        #--------------------------------------------------------
        def _on_post_patient_selection(self, *args, **kwargs):
                wx.CallAfter(self._check_RFE)
        #--------------------------------------------------------

        #--------------------------------------------------------
        def _check_RFE(self):
                """
                This gets called when a patient has been activated, but
                only when the waiting list is actually in use (that is,
                the plugin is loaded)
                """
                pat = gmPerson.gmCurrentPatient()
                enc = pat.emr.active_encounter
                if gmTools.coalesce(enc['reason_for_encounter'], u'').strip() 
!= u'':
                        return
                entries = pat.waiting_list_entries
                if len(entries) == 0:
                        if self.__last_patient is None:
                                return
                        if self.__last_patient != pat.ID:
                                return
                        rfe = self.__last_comment
                else:
                        entry = entries[0]
                        if gmTools.coalesce(entry['comment'], u'').strip() == 
u'':
                                return
                        rfe = entry['comment'].strip()
                enc['reason_for_encounter'] = rfe
                enc.save()
                self.__last_patient = None
        #--------------------------------------------------------

Since passing of time does not evoke a signal from the
database the waiting list would not get updated unless
modified.

I'll add refreshing when patients are changed.
