alt Hacker NewsThe less brilliant thing about the smear is that if your ntpd syncs from smeared and unsmeared servers, the results aren't great.
It would have been better if they would have kept the time on the wire accurate or added mandatory protocol stuff to avoid confusing things for ntpds configured to different leap second handling.

if you need below 1 millisecond time accuracy, probably you know what you are doing and you wont mix NTP servers (and I think you need PTP for that)
