An ntpd is what kept my host within a fraction of a second for five
years with ubuntu 10.04, IIRC, while the absence of it has the same
machine several minutes off in a year under debian 7.8.0. 

On debian, the first thing I've found (prompted by this thread) is the
"ntpdate" package. Its manpage describes invocation in a startup script,
i.e. it's an alternative to ntpd. (And won't act if an ntpd is running.)

It doesn't seem to take any notice of /etc/ntp.conf, but works with a
server specified on the command line.

Aaah, I see the need for the manual/scripted setting of hwclock; ntpdate
doesn't touch that. (ntpd maybe didn't either, but that didn't show.)

Must try openntpd - on another evening.
