12.4 Date & Time
The date and time of the RTC can be set here. The clock has a back-up
battery to keep the time during a power down. Daylight Saving Time (DST) is
supported for the regions Europe and United States.
The Time Server field allows a NTP server to specified. At start up, the Quad-
Core will fetch the time and date from this server. Additionally, an action can
be used to fetch the time. The DST and the Coordinated Universal Time (UTC)
are taken into account when obtaining the time for the NTP server.
The following table lists suggested NTP servers.

based on day of the year, latitude, longitude and UTC. The latitude and longi-
tude values define the position in the world and should be entered in degrees.
The latitude value should be positive for North and negative for South, the
longitude should positive for East and negative for West.
