Name : ntp-refclock
Product : Fedora 37
Version : 0.6
Release : 1.fc37
URL : https://github.com/mlichvar/ntp-refclock
Summary : Drivers for hardware reference clocks
Description :
ntp-refclock is a wrapper for reference clock drivers included in the ntpd
daemon, which enables other NTP implementations to use the supported hardware
reference clocks for synchronization of the system clock.

It provides a minimal environment for the drivers to be able to run in a
separate process, measuring the offset of the system clock relative to the
reference clock and sending the measurements to another process controlling
the system clock.
