TIMEDC(8) | System Manager's Manual | 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).

`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.
