Thanks for reminding me. I don't think I need another demon.
Running a script when I boot -- I shut down at night, boot in
the morning -- will be good enough for me.

This is great, since it seems to indicate that a small fish
like me can use 'pool.ntp.org' without placing undue load
on any of the primary timeservers

These two lines by themselves seem almost perfect.
But I have been trained<g> to check the exit status
of calls. So my script reads:
# This short script follows advice from Richard Rognlie, 25 Aug 08
val=1 # Start off with val a "wrong" value
TIMESERVER="pool.ntp.org" # this URL will give me "some" timeserver!
# val should now be 0 if ntpdate executed correctly
# echo "val is now $val" Debugging!
if [ $val -eq 0 ]; then
echo "Call to ntpdate failed."
(and now actually my call to hwclock fails on my etch machine!)
Anyway, my thanks to Richard, and to Jesse Becker, for their
replies and helpful aid.
