Synchronize system clocks for audit records
Audit and Accountability · NIST SP 800-171 Rev 2
Requirement
Provide a system capability that compares and synchronizes internal system clocks with an authoritative source to generate time stamps for audit records
Discussion
Internal system clocks are used to generate time stamps, which include date and time. Time is expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC. The granularity of time measurements refers to the degree of synchronization between system clocks and reference clocks, for example, clocks synchronizing within hundreds of milliseconds or within tens of milliseconds. Organizations may define different time granulari
