Does anyone know if there is anything like adjtime() available
in HP-UX? I havn't seen anything in the manuals.
Adjtime is used to correct the time and allowing synchronization
of systems clocks in a network by speeding up or slowing down the
system's clock.
What I want is a way to install ntp (Network Time Protocol)
or timed in our HP s300 and s800 machines. We have a network
with several machines from different vendors, using NFS to
share resources. The problem is clock skewness between the
systems.
HP must have thought of synchronizing clocks in a network, and
not just in a cluster. How does the system synchronize clocks
between server and clients in a cluster, anyway? Perhaps one
can use that concept?

The tar file contains the ntp (version 1) source as ported to HP-UX and an adjtime emulator source. The xntp HP-UX port will be available as soon as it is stable. ...tai

Occasionally I use it to resynchronize my clock to WWVB time within a modest number of milliseconds. The daemon (timed) didn't compile, I believe because of BSDisms. Are there others who'd like to use ntp & timed on HP's? If enough popular demand exists I can probably justify using some of my own time to finish the port. ---------------- Paul Raveling Raveling@isi.edu

Ntp (including the daemon, ntpd) has already been ported to HP-UX. I got it with ftp from an .hp.com site last year. It included an implementation for both the s300 and s800. I have been using it since that, and it works great. This port uses a separate process, adjtimed, that emulates the adjtime system call by poking in the running kernel. Ntpd sends requests to this process. -- Tor Lillqvist, working, but not speaking, for the Technical Research Centre of Finland
