I just started running xntpd version 1.3 on my SparcStation last week.
It runs as a stratum 3 client of the campus's three stratum 2 servers.
Each of the campus's stratum 2 servers is peer with a different pair of
off-campus stratum 1 servers, and also the other two campus servers.
At this instant, I have an
xclock -digital -update 1
running on one of the ntp servers, and another on my local workstation.
To my vast surprise, the two xclock's disagree by roughly 15 seconds.
(Unfortunately I don't have accounts on the other two servers.)
Is this normal? I expected them to agree to within a fraction
of a second, not disagree by 1/4 minute.
Would someone with accounts on multiple stratum 2 servers please
repeat my simple experiment?
thanks,
Bill Voss <voss@cs.uiuc.edu>
P.S.
The large delay is because I'm operating over a slip connection, but
even that delay is only a fraction of a second.
