> 2. What are the main differences between SNTP 4 and NTP 4?
NTP (4) has a much more complex interaction between client and server, and
typically a software phase and frequency locked loop on the client. With
SNTP you can send one packet and get the time back in another - and then
your local clock from that. I.e. step the clock and let its rate be
uncontrolled. With full NTP you need rate control of the clock. If a
second ot so would do you for accuracy, SNTP might be enough.
