Check Text (C-263687r982605_chk)

Verify the Mainframe Product is configured to compare the internal system clocks on an organization-defined frequency with organization-defined authoritative time source. If the Mainframe Product is not configured to compare the internal system clocks on an organization-defined frequency with organization-defined authoritative time source, this is a finding.

Fix Text (F-67508r982378_fix)

Configure the Mainframe Product to compare the internal system clocks on an organization-defined frequency with organization-defined authoritative time source.
