Keeping time on an air-gapped network

[Andrew Bacchi]

Here's the NTP web site, where you'll find info on setting up your own 
network time server. http://www.ntp.org/

We have an internal time server, but we do link to a Stratum 2 server 
through a TCP link.  If you absolutely have to be air-gapped, and I 
think a .gov should, you could purchase a highly accurate chronograph 
that would server as your Stratum 2.  You may need to reset that 
annually though.
