Ntp protocol.

The Network Time Protocol (NTP) is one of the most accurate and flexible means of sending time over the Internet. It can be used by almost any type of computer. The protocol is designed to compensate for some, but not all, network time delays between the server and the client. NTP is most successful across local area networks and can give …The ntp.conf configuration file is read at initial startup by the ntpd daemon in order to specify the synchronization sources, modes and other related information.
