IEEE 1588 is a standard for precise time synchronization in networked systems. It enables devices to synchronize their clocks with high accuracy, often in the sub-microsecond range. This is crucial for applications that require coordinated timing, such as telecommunications, industrial automation, and financial trading. The standard defines a protocol that allows a master clock to distribute time information to slave clocks over a network. By using techniques like timestamping and delay request-response, IEEE 1588 ensures that all devices can maintain a consistent time reference, improving the performance and reliability of time-sensitive applications.
