SNTP - Simple Network Time Protocol - is used to synchronize computer clocks on local area networks. This reduces the requirement to have accurate hardware clocks in every embedded system in a network. Each embedded node can instead synchronize with a remote clock, providing the required accuracy.

Interpeak Embedded SNTP is a simplified version of NTP, which can be effectively used at leaves (highest stratum) which require less clock accuracy. It is a fully compatible, portable and efficient implementation of an SNTP client for embedded systems, and is delivered in ANSI compliant C source code with ready-to-run RTOS integration containing makefiles etc.
