SNTP

SNTP (Simple Network Time Protocol) is a simplified version of the Network Time Protocol (NTP) used for synchronizing computer clocks over a network. It provides time synchronization with less complexity and overhead than NTP, typically used in applications where high precision is not critical. SNTP operates over UDP port 123 and is commonly implemented in embedded systems, IoT devices, and basic network infrastructure.

Also known as: Simple Network Time Protocol, SNTPv4, RFC 4330, Time Sync Protocol, Network Time Sync
🧊Why learn SNTP?

Developers should learn SNTP when building systems that require basic time synchronization, such as IoT sensors, network appliances, or applications where NTP's full features are unnecessary. It's particularly useful in resource-constrained environments where minimizing protocol overhead and implementation complexity is important, ensuring devices maintain reasonably accurate time for logging, scheduling, or coordination tasks.
