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. 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.
