SC-45(1)

Control statement

(a) Compare the internal system clocks [Assignment: frequency] with [Assignment: authoritative time source] ; and (b) Synchronize the internal system clocks to the authoritative time source when the time difference is greater than [Assignment: time period].

Discussion

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.
