Quick question about NTP best practice: Local vs External

Hello again Reddit!

I am working on connecting devices on a very small network to NTP in order to get accurate time. It seems like setting up a local NTP server that then connects to external time servers is the preferred way to do it.

What is the motivation for setting up a local server instead of pointing each device on the network to the same one or two external NTP servers, specifically with regards to security. (I understand it is more considerate to the public NTP hosts, but this is a very small network)
