| − | ==NTP Server==
| |
| − | | |
| − | The router can also act as an '''NTP Server''', providing clock synchronization to other devices in the network. From this section you can turn this feature ON or OFF.

| − | ==Time Servers==
| |
| − | | |
| − | The '''Time Servers''' section displays the time servers that the router uses. You are provided with 4 default time servers (as seen in the example below), but you can also add custom time servers by clicking the "Add" button or you can edit the given time servers.
