DESCRIPTION
Implements the Precision Time Protocol (PTP) Version 2 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 v2 specification for a
standard (ordinary) 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.
