Terabithia or compile
I downloaded the source rpm and installed it. The spec file for building the RPMs contains this:
%if %{without trunk}
%if 0%{?rhel} <= 7
Requires: ntp
%endif
%endifSo, yeah, it builds into the binary RPMs the requirement to pull in ntp. I'm not sure if that can be made into a conditional, to require ntp OR chrony.

Installing the xymon package on my server has disabled chronyd and installed (but not started) ntpd. why?! If I hadn't read through the list of packages it was going to grab, and understand the significance of this one, I'd be going blindly forward with an un-synchronized system clock.

I think there's an historical reason for the ntp package being required.
The xymonnet binary uses ntpdate (via NTPDATE defined in xymonserver.cfg) to be able to monitor the "ntp" service. Specifically it execs "ntpdate -u -q -p 1 <host IP>". The code in do_net.c is written around the output of ntpdate, so chronyc couldn't be used as an alternative without some serious munging of the output. So for a base Xymon server deployment, ntpdate is generally required. [Actually, Xymon can use sntp instead of ntpdate, but this isn't actually relevant to the current situation.]
I seem to recall, on earlier (prior to v6) versions of RHEL, that the ntpdate binary used to be part of the ntp (or xntp or xntpd) package. This is probably where the dependency on "ntp" came from.
Installing (the package) ntp also brings in ntpdate (as a prerequisite), but installing just ntpdate should not install ntp. This seems to be the case for RHELv7 and v6. I'd say the spec file should match %{?rhel} between 6 and 7 and do "Requires: ntpdate".

Looks like ntpdate and options are defined in ~/lib/environ.c and ref. in the ~/xymonet/xymonnet.c and ~/xymond/rrd/do_net.c code. Looks like something that needs to be updated, as I'm running a dev xymon server on CentOS 8 and the ntp rpm's are not part of the distro anymore.

When we went for CentOS 8, we simply took the CentOS 7 source RPMs for ntp and rebuilt them for CentOS 8.
There are good reasons why you would want to choose NTP over Chrony in certain corner cases.

Please can you elaborate on when Chrony would not be as good? We're planning on going with chrony rather than trying to bring ntp along for the ride.

It is true that ntp/ntpdate are not part of RHEL 8 at all.
Has anyone gotten it working with the Terabitha RPMs on RHEL 8 yet?
Sounds like there are code changes that are needed to make the 'ntp' checks work correctly, beyond just changing the RPM spec?
Thanks!
