PTP (Precision Time Protocol)

The Precision Time Protocol (PTP) is a method used to synchronize clocks across computer networks with very high accuracy. It ensures that devices like servers, switches, and industrial machines share the same precise time, often within microseconds. PTP achieves this by exchanging timing messages between a master clock and other devices, calculating delays, and adjusting their clocks accordingly. This is essential for applications requiring exact timing, such as financial trading, power grid management, and telecommunications. In essence, PTP keeps devices' clocks aligned so they operate cohesively and reliably in synchronized environments.
