I have the job of testing some remote utility meters that use SNTP to
sync their clocks.  They can't do NTP and the customer is all up in
arms about it.

Customer is overly concerned about accuracy, even though 1 second is
more than good enough for this application.

The meters will be fed from a known good NTP server, on our side of
the firewall.

The customer want us to tell him the clocks are within xxx msec.  What
is the best way?

Packet sniff on port 123?  
I am in a windows environment.

thanks in advance.

Dave
