2.13 Automatic Time Synchronization
Description
When enabled, the system automatically determines and sets the time of day employing Network
Time Protocol (NTP) or ISDN time messages. When using NTP, the system, at ten (10) minute
intervals, requests the time from the specified NTP time server and receives GMT (Greenwich
Mean Time) time. This feature allows the System Time to synchronize with the NTP time server
automatically. If the time deviates more than two (2) seconds, the system clock is adjusted to
match the NTP server.
When using ISDN, the system receives the time of day in ISDN messages and automatically
adjusts the time if the time in the system deviates from the ISDN time.
