Precision Time Protocol (PTP) is a network protocol used to synchronize clocks throughout a computer network. It is designed to achieve high accuracy in timekeeping, often within the sub-microsecond range. PTP is particularly useful in applications where precise timing is critical, such as in telecommunications, financial trading, and industrial automation. PTP operates by allowing a master clock to send timing information to slave clocks over the network. The slaves adjust their clocks based on the received data, ensuring that all devices maintain a consistent time. This synchronization is essential for coordinating activities and processes across various systems.
