The purpose of the IEEE 1588 Precision Time Protocol (PTP) is to synchronize the time between different nodes on an Ethernet network. Many applications in factory automation, test and measurement, and telecommunications require very close time synchronization. This requirement is often well beyond what can be provided by a standard software solution.

About PTP
The IEEE 1588-2002 standard defines a protocol, Precision Time Protocol (a.k.a PTP Version 1), which enables precise synchronization of clocks in measurement and control systems implemented with technologies such as network communication, local computing, and distributed objects. The PTP applies to systems communicating by local area networks supporting multicast messaging, including (but not limited to) Ethernet. This protocol enables heterogeneous systems that include clocks of varying inherent precision, resolution, and stability to synchronize. The protocol supports system-wide synchronization accuracy in the sub-microsecond range with minimal network and local clock computing resources.
