Linux ntp time server configuration tutorial, ntp server configuration

" now we know how to set the system and hardware time. but the question is, what should I do if neither of these two times is accurate? Then we need to find a server on the Internet that can provide our accurate time and then synchronize our system time through a protocol. Then this protocol is NTP. note that next we will talk about synchronization between the system time and the network
