DESCRIPTION
       Implements the Precision Time Protocol (PTP) as defined by the IEEE
       1588 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.

OPTIONS
       -?     display a short help text

       -c     run in command line (non-daemon) mode

       -f FILE
              send output to FILE

       -d     display stats

       -D     display stats in .csv format

       -x     do not reset the clock if off by more than one second

       -t     do not adjust the system clock

       -a NUMBER,NUMBER
              specify clock servo P and I attenuations

       -w NUMBER
              specify one way delay filter stiffness

       -b NAME
              bind PTP to network interface NAME

       -u ADDRESS
              don't multicast, send messages unicast to ADDRESS

       -l NUMBER,NUMBER

              specify sync interval in 2^NUMBER sec

       -m NUMBER
              specify max number of foreign master records

       -g     run as slave only

       -p     make this a preferred clock

       -s NUMBER
              specify system clock stratum

       -i NAME
              specify system clock identifier

       -v NUMBER
              specify system clock allen variance

       -n NAME
              specify PTP subdomain name (not related to IP or DNS)

       -k NUMBER,NUMBER
              send a management message of key, record, then exit
