NAME

       ptpd - Precision Time Protocol daemon (1588-2008)

SYNOPSIS

       ptpd [?]  [-c] [-S] [-f FILE] [-R FILE] [-d] [-D] [-x] [-M NUMBER] [-t] [-T ttl] [-a NUMBER,NUMBER] [-w NUMBER] [-b NAME] [-u ADDRESS] [-e]
       [-h] [-l NUMBER,NUMBER] [-o NUMBER] [-i NUMBER] [-n NUMBER] [-y NUMBER] [-m NUMBER] [-g] [-v NUMBER] [-r NUMBER] [-s  NUMBER]  [-p  NUMBER]
       [-q NUMBER]

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.
