The easiest is probably to configure the GPS refclock into a private
ntpd instance running on a hidden port.  Another exposed ntpd then runs
in lockclock mode and serves the system time controlled by the hidden
instance.

BTW, just got info from the PTB NTP guys that they never used lockclock
mode in production.  Their NTS testbed uses it at the moment, however.
They are quite interested in NTPsec implementing NTS since they consider
offering an NTS service soon.

Achim.
