2.10 AUTOMATIC SYSTEM 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
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.
Operation
System
Operation of this feature is automatic.
Conditions
1. NTP packets are expected over UDP port 123. Assure this port is open and
available.
2. A secondary NTP server address can be defined should the first server not respond.
3. The system adjusts for the local time zone assigned in the system as the Standard
System Time as well as Daylight Savings Time (DST), if set.
