Yes.  This should make it clear why alarmDateAndTime is needed
for the alarmActiveTable (it supports the ordering required for the
most common use cases) and not for the alarmActiveVariableTable
(these are meaningful only in the context of the alarm "containing"
these variables, and a time stamp is not needed to provide uniqueness.
