The NTP service automatically sets the FB2900's real-time-clock using time information provided by a Network Time Protocol (NTP) server. There are public NTP servers available for use on the Internet, and a factory reset configuration does not specify an NTP server which means a default of ntp.firebrick.ltd.uk. You can set your preferred NTP server instead.

The NTP service is currently only an NTP client. A future software version is likely to add NTP server functionality, allowing other NTP clients (typically those in your network) to use the FB2900 as an NTP server.

Configuration of the NTP (client) service typically only requires setting the timeserver attribute to specify one or more NTP servers, using either DNS name or IP address. The default is to use suitable time servers and set the clock automatically with no config needed.

The FB2900 includes a real time clock that can also retain time with no power for a short period. This allows it to start with the right time after a short power outage.
