Checks whether the value of the default_time_zone parameter of each PolarDB cluster is the same as the value of the System parameter. If not, the evaluation result is Compliant.
Scenarios
This rule applies when you need to configure the same time zone settings for the databases of a PolarDB cluster. This ensures that the time zone settings for all databases in a PolarDB cluster are consistent and prevents your business from being affected due to inconsistent time zone settings.
Risk level
Default risk level: high.
When you configure this rule, you can change the risk level based on your business requirements.
Compliance evaluation logic
- If the value of the
default_time_zoneparameter of each PolarDB cluster is different from the value of theSystemparameter, the evaluation result is Compliant. - If the value of the
default_time_zoneparameter of each PolarDB cluster is the same as the value of theSystemparameter, the evaluation result is Incompliant. For more information about how to remediate an incompliant configuration, see Incompliance remediation.

Incompliance remediation
Set the default_time_zone parameter of a PolarDB cluster to a value that is different from the value of the System parameter. For more information, see Specify cluster and node parameters.
