Description

Chrony is a versatile NTP implementation that provides accurate time synchronization. Accurate system time is critical for security logging, authentication, and forensic analysis.

Rationale

Time synchronization is essential for correlating events across systems, validating Kerberos tickets, and ensuring accurate timestamps in audit logs. Chrony is the recommended time synchronization daemon for RHEL.
