As a second option, you may adjust the clock at once with an NTP server using the Internet
connection. In the pop-up windows you have to set-up appropriate NTP servers.
Alternatively the time can be set manually, and this works in every situation (i.e. without
connection to the Internet).

Network (NTP) means that the clock will continuously be synchronized using the Internet
connection. 1 to 4 NTP servers can be specified. The more servers are used, the better
precision is get.
It takes a variable time period – depending on the difference of the internal clock and the
accurate time – to synchronize the clock once a valid NTP server is set-up and Internet
connectivity is available. If the synchronization was successful, the time of the
synchronization is shown as Last clock update in the Status section.
The accuracy of the synchronization depends on the quality of the Internet connection, and
also of the servers you choose. The closer you are to the servers, the better precision you
get.
The 4 default servers (0.pool.ntp.org, 1.pool.ntp.org and so on) are in fact 4 servers
randomly picked up around the world. It always works, but if you want a better accuracy, you
should put in these fields servers from your country. For example, if the SB is in Switzerland,
you should set the 4 servers to 0.ch.pool.ntp.org, 1.ch.pool.ntp.org and so on.
You can find more information about the NTP servers available in your country on the Web
site pool.ntp.org.

If you ordered the GPS option with your SB, you need to select that. Then the SB will keep
its time synchronized with the GPS time, the accuracy being around 1ms.
