This was created and tested using CentOS 7.6

Using NTP so sync CentOS is fairly straightforward, and all you need is an NTP source, of which there are many. However occasionally, it is advantageous to have your NTP source and clients all local.

NTP is more about ensuring the correct operation of a system, rather than just having the correct time (with exceptions of course, scheduling, SCTE really require accurate time).

In this example, I have three CentOS systems, and the first will be the NTP server, with the second two being NTP clients. I did this for a Split ABR Encoding system, so I did not have to rely on any external NTP servers.
