Chronyd Time Server Synchronization time configuration

Chrony is the two program used to maintain the accuracy of computer system clocks, both of which are named Chronyd and Chronyc.

Chronyd is a daemon that runs in the background of the system. He adjusts the system clock by measuring the offset of the local time based on other time server time on the network. For orphaned systems, the user can manually enter the correct time periodically (via CHRONYC). In both cases, the chronyd determines the ratio of the speed of the computer and corrects it. CHRONYD implements the NTP protocol and can act as a server or client.

CHRONYC is a user interface for monitoring chronyd performance and configuring its parameters. He can control the CHRONYD processes running on the machine and other computers.
