This document is intended to provide the reader with the necessary steps to programme Automatic Time Synchronisation.

 

Automatic Time Synchronisation

 

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 requests the time from the specified NTP time server and receives GMT (Greenwich Mean Time) time at 10 minute intervals.  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.
