MariaDB must record time stamps, in audit records and application data, that can be mapped to Coordinated Universal Time (UTC, formerly GMT).
An XCCDF Rule
Description
<VulnDiscussion>If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by MariaDB must include date and time. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC. Some DBMS products offer a data type called TIMESTAMP that is not a representation of date and time. Rather, it is a database state counter and does not correspond to calendar and clock time. This requirement does not refer to that meaning of TIMESTAMP.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
On the OS command line run the following command to get the time zone the system is in:
date | awk '{print $5;}'
If the system is in UTC, to set the time zone for timestamps to UTC, modify the MariaDB configuration file located within /etc/my.cnf.d/ and set the variable time_zone to SYSTEM under the server section. Restart MariaDB Enterprise Server.
