SC-45(1): Synchronization with Authoritative Time Source
(Not part of any baseline)
Control is new to this version of the control set and incorporates the following control from the previous version: AU-8(1): Synchronization With Authoritative Time Source.
- Compare the internal system clocks [Assignment: organization-defined frequency] with [Assignment: organization-defined authoritative time source]; and
- Synchronize the internal system clocks to the authoritative time source when the time difference is greater than [Assignment: organization-defined time period].
Synchronization of internal system clocks with an authoritative source provides uniformity of time stamps for systems with multiple system clocks and systems connected over a network.
