February 2, 2007 TIMEDC 8

### NAME

timedc - timed control program

### SYNOPSIS

timedc [command[ argument ...]]

### DESCRIPTION

timedc is used to control the operation of the timed(8) program. It may be used to:

- Measure the differences between machines' clocks,

- Find the location where the master time server is running,

- Enable or disable tracing of messages received by timed(8), and

- Perform various debugging actions.

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.

msite[ host ...]
  Show the master time server for specified host(s).

Xo
  trace ```{` on```|` off } Enable or disable the tracing of incoming messages to timed(8) in the file ```/var/log/timed.log`.

election host
  Asks the daemon on the target host to reset its ``election'' timers and to ensure that a time master has been elected.

quit
  Exit from timedc.

Other commands may be included for use in testing and debugging timed(8); the help command and the program source may be consulted for details.
