This article will guide you on how to configure the NTP server on the #Ubuntu machine and then sync a clock of NTP client machine. Now you can easily set up NTP server and connect multiple client machines with it for time synchronization.
The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.
NTP is intended to synchronize all participating computers to within a few milliseconds of Coordinated Universal Time (UTC).
How do I start #NTP on Linux?

What port does NTP use?
NTP time servers work within the TCP/IP suite and rely on User Datagram Protocol (UDP) port 123. NTP servers are normally dedicated NTP devices that use a single time reference to which they can synchronize a network.
This time reference is most often a Coordinated Universal Time (UTC) source.

1. Edit the /etc/ntp.
2. Search for the lines beginning server .
3. Replace the server entries with the IP address or hostname of the NTP server or servers with which you want to synchronize.
4. Save the file.
