3.10 Configuring the Time Source (SNTP)
The time and date can be entered into the Horizon system. This is maintained for as long as power is
applied to the system. If power fails, then all timing information is lost. An accurate clock is necessary for
time stamping entries in the events and performance logs.
To maintain the time and date in the system, five network sources of timing information are configurable.
Up to five time sources can be configured, which can provide accurate time and date information to the
system. Simple Network Time Protocol (sntp) is used.
Five time sources are configured by default. Each time source is indexed 1 to 5. Indices 1 and 2 are from
Industry Canada servers, 3 and 4 are from U.S. Navy servers and 5 is from a Swiss server. Any other
time sources can be configured. The timing information is polled every 60 minutes.
