Having been a participant on Standards Working Groups, I understand
completely.  Regulations, like Standards, need to be written to apply to
as wide a population as possible.  Do those regulations dictate how you
monitor drift?  For example, can you have a system (I would use CentOS)
that syncs to the appliance as well as NIST and your inside NTP sources,
and use ntpq(8) to read the drift directly?
