There seem to have been a lot of questions asked in the last month that

Precision -7 is poor, but possibly a contra-indication for the main
hypothesis as I believe that w32time is normally even worse, at -6.

Hi,
Does an NTP servers take into account it's estimated offset in serving time
to others? If I am a server and think I am 1.5 milliseconds off from true
time, will I include this in the timestamps of my ntp replies to others?
Thanks
