First, select the server base clock, you can select the internal hardware clock and external NTP timing server. (Make sure your time is accurate first)

1. Introduction to NTPNTP, Network Time Protocol, is a protocol that is used to synchronize the time of each computer in a network. Its purpose is to synchronize the computer clock to the World coordinated UTC, its accuracy in the LAN up to 0.1ms, in most places on the Internet its accuracy can reach 1-50ms.NTP servers provide time synchronization services using
Take the RHCE lab as standard. A simple NTP time server standard configuration is as follows: (Fu) server side: first, modify the system time and write the system time into dateMMDDhhmmYYYY in the hardware

When you run Ntpdate, it broadcasts first, and then listens on port 123.If XNTPD is running and a process is already listening on that port, it will cause ntpdate to fail to run on it.

Ntp service and time synchronizationI had a small project that was completely self-developed. I thought it was a very simple NTP service.
