The PTP daemon (PTPd) Project implements the Precision Time Protocol (PTP) specification as defined by the relevant IEEE 1588 standards. PTP Version 1 is specified by IEEE-1588-2002, and PTP Version 2 is specified by IEEE-1588-2008. PTP was developed to provide very precise time coordination of LAN connected computers.
PTPd is a complete implementation of the IEEE 1588 specification for standard (non-boundary) clocks. It has been tested with and is known to work properly with other IEEE 1588 implementations. The source code for PTPd is freely available under a BSD-style open-source license. Thanks to contributions from users, it is an increasingly portable, interoperable, comprehensive, and stable IEEE 1588 implementation.
PTPd can run on most 32- or 64-bit, little- or big-endian processors. It does not require a Floating Point Unit (FPU), so it is great for embedded processors. It currently runs on Linux, uClinux, FreeBSD, and NetBSD. It should also be easy to port to other platforms.
PTPd is free (open-source) software. Everyone is welcome to use and contribute to the PTPd Project. You can learn more at the PTPd project’s website, and you can support the PTPd project by joining and participating in Network Time Foundation’s PTP Consortium.
