Implements the Precision Time Protocol (PTP) as defined by the IEEE 1588-2008 standard. PTP was developed to provide very precise time coordination of LAN connected computers.

PTPd is a complete implementation of the IEEE 1588 specification for a standard (non-boundary) clock. PTPd 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 license. Thanks to contributions from users, PTPd is becoming an increasingly portable, interoperable, and stable IEEE 1588 implementation.
