linuxptpprosjektet

linuxptpprosjektet is an open-source software project that provides an implementation of the Precision Time Protocol (PTP) for Linux systems. It is designed to enable precise time synchronization across networked devices by leveraging the IEEE 1588 standards and, where hardware support is available, Linux kernel clock hardware (PHC) timestamps.

The project supplies a set of user-space tools that form a complete PTP solution. The core daemon, ptp4l, participates in the PTP protocol to synchronize a clock with a master clock over a network. Supporting utilities include phc2sys, which synchronizes either the system clock or a hardware clock (PHC) to a PTP clock, and pmc, a management client used to configure and query PTP clocks. Together, these tools allow both software and hardware clock synchronization across diverse network environments.

linuxptpprosjektet supports the Precision Time Protocol as defined by IEEE 1588, and it is designed to work with Linux systems that provide kernel support for PTP clocks (PHCs) and hardware timestamping. This enables low-latency, high-accuracy time distribution suitable for applications in telecommunications, financial systems, industrial automation, and research contexts that require coordinated timing.

Historically associated with the linuxptp project, linuxptpprosjektet is developed and maintained by a community of contributors, with key influence from researchers and practitioners in time synchronization. The software is released under an open-source license (GPL), and is hosted by the broader linuxptp community. It is commonly deployed in environments where precise clock synchronization is essential and serves as a practical alternative or supplement to network time protocols in Linux ecosystems.
