Dear all,
I'm rather new to NTP so please forgive me, if my question is trivial.
I'm maintaining a legacy system with its own proprietary time
synchronisation protocols. Now I want to add a new subsystem which
requires a NTP daemon to be available. I have added a gateway device
which will be used to run an NTP daemon to provide NTP based time
synchronisation to the newly added subsystem.
My questions are:
1. I want to use my legacy time synchronisation protocol/mechanism as the
reference clock of the NTP daemon on the gateway device. In my limited
understanding this means that the NTP daemon on the gateway would become a
stratum 1 server, right? Are there ways to "easily" add new reference
clocks in popular implementations like ntpd preferably without setting the
system time on the gateway?
2. Is it possible to prevent ntpd on the gateway from setting the system
time on the gateway?
3. What are the ramifications in view of this being a certified system?
( just guessing, is this something that has a "Bahntechnische Zulassung" ? )
