Sorry do not understand NTP
NTP stands for "Network Time Protocol "
I've tried to find something on the Internet
What I found was.
NTP is often used in routers and computers. Do we have multiple devices on a LAN, using NTP, since one can usefully include a computer, or perhaps more smart router running as a local NTP server for other units, and just let this one unit to synchronize to an NTP server Internet.
So I can use NTP to synchronize all of my computer on my network.
