  NTP version 1 is really old.  They should upgrade from using ntpd(8)
to using xntpd(8) using the freely distributable sources available via
anonymous ftp from /pub/ntp on louie.udel.edu (the official xntp3
archive site).

  I know that xntp3 has been ported to AIX machines because the
University of Virginia is running xntp3's xntpd(8) on their AIX
RS/6000 machines.  I assume it compiles "out of the box" but haven't
checked that personally since I have no AIX machines myself.  It does
compile out of the box and run fine on HPUX-based HP 700 systems.  I
haven't tried it under HP's B1-targeted operating system but might if
time permits during 1993 (I expect it will be tricky to port with
least privilege because of BLS kernel permissions and other MAC issues).

  I'd recommend migrating all of the machines to using the xntpd from
the xntp3 distribution.  I've migrated all but one of the machines in
my area of the lab to xntp3 and have talked several other parts of the
lab into using xntp3 as well.  

  Having really accurate time turns out to be essential in networking
research (and probably also is helpful in debugging networks) because
you can time correlate various events on the research (or operational)
network to help figure out how things are behaving and interacting.
It also is essential to get accurate performance measures.
