I'm using the Meinberg NTP Distribution here with their NTP Monitor prog on Win10-64, and two GPS NTP servers.
Config settings: - server 192.168.1.120 iburst minpoll 4 maxpoll 5 server 192.168.1.121 iburst minpoll 4 maxpoll 5 Consistent sub millisecond results. I've also found that Win10 actually performs way better than Win7.

I use the Meinberg disturb of NTP. My client’s offset from the paris observatory is less than a millisec. Maybe you should check your NTP status and see what offset you get from a known good source with ntpdate -b -d <name or IP>. > Le 11 oct. 2017 à 13:29, Chris Wilson <ch...@chriswilson.tv> a écrit : > > > > 11/10/2017 12:24 > > Probably a simple answer, but I am curious as to why my PC clock > which is set by NTP on Windows 7 64 bit OS is ahead of Lady Heather's > time, locked to a Trimble Thunderbolt by about half a second > (guesstimate..)
