8.3.1.1 Setting the System Date and Time
New in CPU-7 is the ability to time off the network via an SNTP server. This option is
normally disabled, and is accessed via the normal method of setting the time on the shelf. Go
to the Interface card screen, and then select "T" for time. The SNTP screen comes up as shown
in the composite image below and the customer can choose to use this as the timing option or
select "set Time" from this window to set the time in the traditional manner. Choosing the
SNTP option allows the IMACS shelf to maintain the time of day clock in configurable time
intervals. Using the traditional time of day methods would leave the IMACS to keep the time
of day based on its own system clock, which would eventually lead to a time of day difference
between the system time of day and the real time of day. Choosing the SNTP option allows
the system to track it’s time of day clock to an external source, leading to a much improved
reflection of the system time of day and the actual time of day. This offering of an SNTP server
is based off of version four (v.4) of the SNTP protocol.
