SC-45(2) Secondary Authoritative Time Source
Control enhancement of SC-45 System Time Synchronization
Control
Identify a secondary authoritative time source that is in a different geographic region than the primary authoritative time source; and
Synchronize the internal system clocks to the secondary authoritative time source if the primary authoritative time source is unavailable.
Discussion
It may be necessary to employ geolocation information to determine that the secondary authoritative time source is in a different geographic region.
