I've downloaded the xntp+hp-1.30 code from an HP archive
for my HP 9000.  I guess I'm a little unclear on the big picture.
There are two HP 9000's and 3 RS6000's here as well as a dozen PC's
and OS/2 machines.  Do I compile ntp for each of the workstations
and get them to lock onto one station acting as the standard?

My second question is I also have a Heath World's Most Accurate Clock,
picking up WWV's signal from Boulder.  We have an RS-232 port on the
clock that continually updates at 2400 baud.  We feed it into a PC
COM2 and use the signal to adjust the time for the PC driving the
satellite tracking system.  
 1. Can ntp use the output of WMAC, as two recent posters have asked?
 2. If I got an authoritative time on the workstation, could the WS
    output the signal to the PC?

Is this program specifically for getting your local systems in sync or 
can you connect thru the Internet to NIST.GOV or utoronto.edu or
udel or some stratum 1 site to get an authoritative time-code?

Lastly, is this really necessary for our site?  We definitely need a
good timecode to drive the satellite dish from the PC.  We adjust
the time manually to the readout of WMAC occaisionally.  It doesn't
really matter for our applications that the time stamps are correct.
Is this a "nice-to-have" rather than a "need-to-have" for us?

I'd appreciate any comments.
