You can configure the clients with the peer directive instead of
server directive to disable the transmit timestamp randomization.

A better way to monitor the clients would be to enable them as NTP
servers and specify them as servers with the noselect option on the
monitoring node. This way you would get a better estimate of their
error, compensated and filtered for the network delay.
