4.4.3 Automatic Time Adjustment
Description
It is possible to adjust the Control Box's clock automatically in the following two ways:
a.
Summer Time (Daylight Saving Time) Setting:
The start and end dates of the summer time can be programmed. The clock will be adjusted (one hour
forward or backward) at 2:00 AM of the programmed date, if enabled through system programming. It
means 2:00 AM will become 3:00 AM on the start date of the summer time, and 2:00 AM will become
1:00 AM on the end date.
b.
Time Information through Network Time Protocol (NTP):
By connecting the Control Box to an NTP server, it is possible to receive and update the time setting.
The clock will be adjusted every day at 3:05 AM, if enabled through system programming.
Conditions
•
SMDR will record the call information using the Control Box clock so that the recording time will be
overlapped at the end of summer time.
