The RADclock client seems to be designed for LAN environments, at
least the current version. It misses multiple source support and
falseticker detection which is important in our default config, as
the quality of pool.ntp.org servers varies a lot.

However, many of the ideas they use are used in chrony too. I'd not be
surprised if chrony configured for LAN performed similarly well as
RADclock (in terms of absolute clock).
