Running a time server in your network
There are two ways to keep exact time on all computers in your network.
One way is to keep atomic time synchronizer on each computer in your network.
In this case, every computer should be able to access Internet.
Also computers will be slightly unsynchronized from each other.
Another way is to setup a time server on your server computer and
keep all other computers synchronized with this server. Time server will synchronize
with atomic time servers (you should set it to synchronize automatically at regular intervals).
