On the time server machine, I am currently using ntpdate to acquire
remotely the time offset of my unsync'd systems. nptdate works for this
application (calculating and printing the time offset). And yes, you are
also right, it refuses to sync. :-)
# /usr/sbin/ntpdate -q 10.0.0.100
server 10.0.0.100, stratum 16, offset -0.727935, delay 0.03511

My use case is not to sync but only to get the time offset (in order to
calculate the skew). As ntpdate will be retired soon from the official
distribution, I'd suggest that maybe sntp could behave in the same way
as ntpdate does: acquire the time offset (including uttering complaints)
but refuse to sync (command line options -r or -a?).
