NTP has been ported to HP-UX and is running quite well.  The adjtime(2)
call is not currently supported in HP-UX, but it is possible to emulate
the functionality in HP-UX 6.0/2.0 and later (there is no guarantee that
this will work in the future).  And instead of the setpriority(2) call,
you could use rtprio(2) instead.  This is not an exact match, but it
should work.

I should caution you about using rtprio(2) in a network application.
There is a daemon called netisr which handles lowlevel network I/O.  This
daemon runs with the lowest real-time priority by default.  And it is
important that netisr be running with a higher real-time priority than all
network applications.  So if any network applications run at real-time
priority then you should increase netisr's priority.
