The **Network Time Protocol** lets you synchronize the system time over the network.

You can **enable** or disable it completely and define whether it uses all **interfaces** or a subset.
The **orphan mode** is 12 by default and allows a group of ntpd processes to automonously select a leader in the event so that all real time sources become unreachable.
With **Logging Peer Messages** you can enable additional peer log information and with **Logging System Messages** additional system log information.

A variable number of time servers can be added, each with a **server address**.
If you select **prefer**, this time server will be chosen before other servers when all other settings are equal.
The option **no select** marks the server as unused, except for display purposes.
