DESCRIPTION

The timedc command is used to control the operation of the timed program.  It
may be used to:

  o measure the differences between machines' clocks
  o find the location where the master time server is running
  o enable or disable tracing of messages received by timed
  o perform various debugging actions.

Without any arguments, timedc prompts for commands from the standard input.  If
arguments are supplied, timedc interprets the first argument as a command and
the remaining arguments as parameters to the command.  The standard input may
be redirected causi n timedc to read commands from a file.  Commands may be
abbreviated.  Recognized commands are:

? [ command ... ]      Prints a short description of each command specified in
                       the argument list or if no arguments are given, a list
                       of the recognized commands.

help                   Prints a short description of the specified command(s),
                       or if none are named, a list of the recognized commands.

clockdiff host ...     Computes the differences between the clock of the host
                       machine and the clocks of the machines given as
                       arguments.

election host          Causes the election timers of the time servers on the
                       named hosts to expire.  This is used to test the
                       functions which cause a new master to be elected.

msite                  Prints the hostname of the current master time server.

quit                   Exits from timedc.

trace ( on | off )     Enables or disables the tracing of incoming messages to
                       timed in the file /usr/adm/timed.log.

EXAMPLES

To list commands:

  $ timedc help

Commands may be abbreviated.  Commands are:

  clockdiff        help     quit       ?
  election         msite    trace

To measure a clock difference against 1 other host:

  $ timedc clockdiff host2
  time on host2 is 53 ms. ahead of time on host1

To measure clock differences of all sites in the cluster:

  $ timedc clockdiff `ptn`
  time on host1 is   ms. ahead of time on host1
  time on host2 is 53 ms. ahead of time on host1
  time on host3 is 28 ms. behind time on host1

To turn timed tracing on:

  $ timedc trace on
  timedc tracing enabled

Interactive use:

  $ timedc
  timedc> clockdiff host2
  time on host2 is 27 ms. behind time on host1
  timedc> trace off
  timed tracing disabled
  timedc> quit

FILES

/usr/adm/timed.masterlog
                       log file for master timed.

/usr/adm/timed.log     file that logs messages from timed and timedc.
