[time-nuts] Typical NTP performance? Monitoring multiple NTP servers?

[Harlan Stenn]

Anders,

It's possible to discipline the local clock with PTP and have NTP serve
that time to other hosts if that's what you want to do.

It's easy to have a single local NTP instance track multiple remote NTP
instances.  Preferred, even.

I routinely see LAN machines running NTP that track time to 1ms or
better using just the network - no PPS.

Others here will likely have better information for you.
