Displaying and resetting system time
The system date and time for the MCU can be set manually or using the Network Time Protocol (NTP).
To configure Time settings, go to
Settings > Time
.
Note that changing the time or NTP settings will have an effect on the recorded times in the Call Detail
Records log. For more information, refer to

NTP
The MCU supports the NTP protocol. Configure the settings using the table below for help, and then click
Update NTP settings.
Update NTP settings.
The MCU re-synchronizes with the NTP server via NTP every hour.
If there is a firewall between the MCU and the NTP server, configure the firewall to allow NTP traffic to UDP

port 123.
If the NTP server is local to Port A or Port B then the MCU will automatically use the appropriate port to
communicate with the NTP server. If the NTP server is not local, the MCU will use the port that is configured
as the default gateway to communicate with the NTP server, unless a specific IP route to the NTP server's
network/IP address is specified. To configure the default gateway or an IP route, go to
communicate with the NTP server. If the NTP server is not local, the MCU will use the port that is configured
as the default gateway to communicate with the NTP server, unless a specific IP route to the NTP server's
network/IP address is specified. To configure the default gateway or an IP route, go to

UTC
offset
offset
The offset from the time zone that you are in
from Co-ordinated Universal Time (UTC).
UTC is in broad terms equivalent to
Greenwich Mean Time. The offset allows you
to set a local time appropriate to the
geographic location of the MCU and/or
adjust for daylight saving.
from Co-ordinated Universal Time (UTC).
UTC is in broad terms equivalent to
Greenwich Mean Time. The offset allows you
to set a local time appropriate to the
geographic location of the MCU and/or
adjust for daylight saving.
The offset can be -12:59 to 14:59 hours and can be set
in the format hh:mm (or -hh:mm for negative offsets) to
specify locations that vary from UTC in half hours. For
example, for Rangoon which is six and a half hours
ahead of UTC, the offset is 6:30. You do not need to
enter the minutes for whole hours, so an offset of one
hour is 1.
