1.1.7 Automatic Time Adjustment
Description
The PBX clock can be adjusted automatically in the following two ways:
1. Daylight Saving Time Setting
The start and end dates of Daylight Saving Time can be programmed. The PBX clock will automatically
adjust itself one hour
forward or backward at 2:00 A.M. on the programmed date, if enabled through system
programming. At 2:00 A.M. on the start date, the clock will change to 3:00 A.M., and at 2:00 A.M. on the
end date, the clock will change to 1:00 A.M.
Note
If a Timed Reminder (Remote Wake-up call) is set:
– On the Daylight Saving Time start date, a reminder set for between 2:00 A.M. and 3:00 A.M. will
not ring.
– On the Daylight Saving Time end date, a reminder set for between 1:00 A.M. and 2:00 A.M. will
ring twice.
2. Time Information from Telephone Company
Time information can be received when
– An incoming or outgoing call through an ISDN line is received/made.
– An incoming call through an analog line with Caller ID which includes time information is received.
The PBX clock will be adjusted everyday with the first call after 3:05 AM, if enabled through system
programming.
Note
If a Timed Reminder
(Remote Wake-up call) is set, the setting will not ring or will ring twice depending
on the adjustment.
3. Time Information through Simple Network Time Protocol (SNTP)
By connecting the PBX to an SNTP server, it is possible to receive and update the time setting. The PBX
clock will be adjusted everyday at 3:05 AM, if enabled through system programming.
Conditions
[General]
• Through system programming, it is possible to specify SNTP, ISDN, or neither method as the selected
method of automatic time adjustment.
• Station Message Detail Recording (SMDR) will log call information using the PBX clock so that the logging
time will be overlapped at the end of Daylight Saving Time. (® 16.1.4 SMDR (Station Message Detail
Recording))
