With a closed network the options are limited. With a place to site a
GPS antenna, you can install a GPS clock that will be accurate to within
+/- 50 nanoseconds. Getting the time into the computer will degrade the
time somewhat but it should still be usable. Various radio clocks are
available: WWV, WWVA, WWVB, CHU, JJY and more. These may require an
antenna somewhat larger than a GPS antenna. :-)
