Time
The time settings on the web interface allow you to configure the NTP server address for automatic time and date synchronization. Once a time zone is selected, the device will notify the NTP server of the chosen time zone, enabling it to synchronize the time zone settings on your device.
To set it up, go to the Setting > Time/Lang interface.

Automatic Date&Time Enabled: Set whether the device updates the time automatically via the Network Time Protocol(NTP) server.
Time Zone: Select the time zone.
Primary/Alternate Server: Enter the primary NTP server address for updating the time. The default NTP server address is 0.pool.ntp.org. The alternate server is for backup.
Update Interval: Set the time update interval. For example, if you set it to 3600s, the device will send a request to the NTP server for the time update every 3600 seconds.
Current Time: Display the current device time.
