Simple network time protocol definition
Simple network time protocol, or SNTP, refers to a protocol used to synchronize the clocks of computers or devices with a trusted time source. It’s a simpler version of the network time protocol (NTP) without the advanced error-checking and accuracy features.

Simple network time protocol vs network time protocol?
- Single source. SNTP asks just one trusted source for the time, while NTP syncs across multiple sources.
- No double-checking. SNTP gets the time and sets it without worrying if the time is a little bit off. NTP, on the other hand, double-checks and tries to get the most accurate time possible.
- Simplicity. SNTP is easier to use because of its simplicity, but it might not be as exact as NTP.
Where is simple network time protocol used:
- Consumer electronics. Devices like smart TVs and Blu-ray players may use SNTP because they don’t need time with split-second accuracy.
- Network devices: Devices like basic routers, switches, or other networking hardware might use SNTP for logging or other time-based functions.
- Home appliances. Modern smart appliances, such as refrigerators, washing machines, or ovens with digital interfaces, could use SNTP to keep track of time.
- Basic digital clocks. Some digital wall clocks or alarm clocks use SNTP to auto-set or correct the time.
