The internal clock in iPocket 232 s 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.
iPocket 232 s only support SNTP in unicast mode. In unicast mode, the client (iPocket 232 ) sends a
request to a designated server or servers and waits for a reply.
You can configure up to two SNTP servers. The iPocket 232 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.
