You say: "All boxes connect up to it for synchronization of time". Do you
mean that all boxes run the NTP software as a client to the FreeBSD box
(this is the way in which NTP is normally deployed), or that once every so
often all boxes go and get the time from the FreeBSD system, and then just
drift at random? If the latter, then NTP isn't controlling all boxes, if
the former than you have an issue. What OS is running on "all boxes"?
