Be aware that if the hope is that the private network be immune to
hacking from the public network, or immune to leakage of information
from private to public, there cannot be a computer common to both
networks.  

There are hardware solutions to this dilemma, specifically GPS
receivers with built-in isolated NTP servers, each server with its own
dedicated  ethernet port.
