Abstract :
This paper proposes a small SNTP server to set the correct time for in-home electric appliances. In-home electric appliances obtain the correct time through the Internet by using SNTP. The proposed method was implemented in a verification system with an embedded microprocessor, RTOS and the small resources of 1.8 MB which are assumed to be required for consumer use and was verified. As a result, the correct time was provided with a precision within 1 ms for an SNTP server, and the RTC was able to set it.
