说明
chrony is a versatile NTP (Network Time Protocol) implementation for synchronizing system clocks. It consists of chronyd (daemon) and chronyc (command-line interface). chrony excels in challenging environments: intermittent network connections, virtual machines with unstable clocks, and systems that sleep or hibernate. It synchronizes faster than ntpd and maintains better accuracy in variable conditions. Configuration is in /etc/chrony.conf (or /etc/chrony/chrony.conf), specifying NTP servers, access controls, and clock adjustments. The daemon can operate as both NTP client and server.
