Calculate the difference quotient over the real time which is supposed to
be
monotonically increasing given your time sync setup is correct. If
you
insist on
reading it from cn=monitor it's cn=Current,cn=Time,cn=Monitor.
But for both cases I would be unable to detect a restart of the slapd. Rates
may seem negative then.
