Implementing SNTP

Standards,

The system software provides an SNTP client, which works with
distributed SNTP time servers to synchronize the system clock to
international time standards.
The SNTP client operates in unicast mode, which means that the client
and server end-system addresses are assigned following the usual IP
conventions. Although SNTP in these systems supports one server at a
time, you can define up to three servers for backup. Therefore, when the
client does not receive a response from the first server within a
designated time, it sends a request to the next server on the list.
See the following references for more information on these protocols:
