About the chronyd Service Daemon
The chronyd
service daemon updates the system clock of mobile systems and virtual machines after a period of suspension or disconnection from a network. The service can also be used to implement a basic NTP client or NTP server. As an NTP server, chronyd
can synchronize with upper level stratum NTP servers or act as a stratum 1 server using time signals that are received from the Global Positioning System (GPS) or radio broadcasts such as DCF77, MSF, or WWVB.
In an Oracle Linux 10 system, this service daemon is enabled by default.
Note:
chronyd
uses NTP version 3 (RFC 1305), with features that are compatible with NTP version 4 (RFC 5905). However, chronyd
does not support several important features of NTP version 4, nor does it support the use of PTP.
For more information, see the chronyd(8)
manual page and files in the /usr/share/doc/chrony/
directory.
