NTP Network Time Protocol SDKPac by Cypherbridge Systems is a software development kit that implements the RFC5905 standard NTP protocol for high-resolution network UTC time synchronization. It is a client implementation designed for wide area network applications. The SDK includes timestamp and system clock processing, with algorithms for NTP server polling, clock filtering, and local clock step and slew operations. It supports applications that implement timestamp and system clock processing based on RFC specifications. The SDK is designed to be integrated with the Cypherbridge SDKPac framework, allowing deployment across various platforms, operating systems, TCP/IP stacks, and toolchains. Implemented in portable ANSI-C, it supports a broad range of processors and platforms.
