IIRC, ntpd should not cause large-scale changes to the time that
might wreak havoc with your router. It should only be making changes
in the rate at which the clock ticks, so as to speed it up or slow it
down, to the point where you are more or less in sync with your
reference(s). It would be ntpdate that would be the potentially
dangerous one making large-scale changes to your system time.
Therefore, you definitely want the router stuff before the ntpd stuff.
