5.4 [SNTP CLIENT]
The [SNTP CLIENT] section is used to specify the parameters for the Simple
Network Time Protocol (SNTP) Client provided with the protocol driver.
This client is read in order to keep the driver's internal clock set correctly. This
version of the driver supports SNTP Revision 3 and stratum between 1 and 14.
SNTP is used for time synchronization of produced and consumed commands.
When an exchange occurs the driver compares time stamps from the previous
exchange. When the new exchange time is less than the previous exchange, the
exchange is ignored. This can occur when the Ethernet packets are routed and
delayed. Time synchronization provides for data integrity.
