Technical Notes and Briefs: Differences Between NTP and SNTP NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are very similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The procedure used by the Time Server to assemble and send out a time stamp is exactly the same whether NTP (i.e. full implementation NTP) is being used, or if SNTP is being used. pdf - 64 KB
