The internal clock in iPocket232s will drift slightly over time. With SNTP configured,
the internal clock can be adjusted according to a central time server with an accuracy
of approximately 4 milliseconds.
iPocket232s only support SNTP in unicast mode. In unicast mode, the client
(iPocket232) sends a request to a designated server or servers and waits for a reply.
You can configure up to two SNTP servers. The iPocket232 will attempt to update the
internal clock every five minutes. If the unit is already connected to the network, it
will contact the first server. If the unit is not connected, it will wait until a connection
is established, contact both servers, and accept the first reply. If a reply is not received,
both servers will be contacted on the next attempt.
