This is a simple servo that provides the NTP SHM reference clock. It doesn't make any clock adjustments and it always returns with the unlocked state. It writes all samples to the SHM segment and another process (e.g. chronyd or ntpd) is needed to read the samples and actually synchronize the clock. The SHM segment number is set to the PTP domain number to allow multiple SHM reference clocks running at the same time. This is mainly useful when other time sources are available on the system (e.g. NTP, hardware reference clocks, or other PTP domains) and a fallback to/from PTP is needed.
