C 6 timedc - timed control program /etc/timedc [ command [ argument ... ] ] Timedc is used to control the operation of the timed program. It may be used to: measure the differences between machines' clocks, find the location where the master timed is running, cause election timers on several machines to expire at the same time, enable or disable tracing of messages received by timed.

Without any arguments, timedc will prompt 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 causing timedc to read commands from a file. Commands may be abbreviated; recognized commands are:

? [ command ... ]

help [ command ... ]

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

clockdiff host ...

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

testing host ...

Cause timed election timers to expire in the specified hosts. It is used to test the election algorithm.

tracing { on | off }

Enable or disable the tracing of incoming messages to timed in the file /usr/adm/timed.log.

quit

Exit from timedc.

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