Description
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events. Sources outside the configured acceptable allowance (drift) may be inaccurate.

Check Text (C-257943r1045001_chk)

Verify that RHEL 9 has the chrony package installed with the following command: $ dnf list --installed chrony Example output: chrony.x86_64 4.1-3.el9 If the "chrony" package is not installed, this is a finding.

Fix Text (F-61608r925815_fix)

The chrony package can be installed with the following command: $ sudo dnf install chrony
