.SH 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.
|
|
.PP
|
|
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.
