Precision Time Protocol (PTP)

Precision Time Protocol (PTP) is a method used in computer networks to synchronize the clocks of multiple devices very accurately, often within nanoseconds. It ensures that all devices share a precise common time reference, which is essential for tasks like financial transactions, industrial automation, and telecommunications. PTP works by exchanging timing messages between a master clock and slave clocks, allowing devices to adjust their clocks precisely. This synchronization improves coordination and performance across networked systems, enabling reliable and coordinated operation in environments where timing accuracy is critical.
