Well, no.  On my system it's run whenever I up a network interface.

That seems counter to what the poster requested.  Why run a permanent daemon
if what you want is to just check your time weekly.  Run ntpdate from
cron.weekly, instead.  Most desktop users don't have the need to have their
clocks as perfectly synchronized as ntpd will keep them.  As long as my
alarm daemon notifies me within 30 seconds of the real time, it's good
enough for me.

cron would accomplish that.  Plus, if you're running anacron, it would also
get run (asynchronously) after each boot.
