timedc
timedc(8) System Manager's Manual timedc(8)
Name
timedc - timed control program
Syntax
/usr/etc/timedc [ command [ argument ...]]
Description
The program controls the operation of the daemon. If you run without any arguments, enters interactive mode and displays the prompt.
If you supply a command on the command line, runs the command and then exits. If you redirect the standard input of from an interactive
terminal to a file, interprets the contents of the file as a list of commands separated by carriage returns and terminated with an EOF
character.
Commands
?[command...]
help[command...] Prints a short description of each command specified in the argument list. If no arguments are given, a list of the
recognized commands is printed.
clockdiff[host...] Computes the differences between the clock of the host machine and the clocks of the machines given as arguments.
trace[ on | off ] Enables or disables the logging of incoming messages to The command logs messages in the file
[ incr | decr ] [ -cd ][minutes:][seconds.][microseconds]
Increments or decrements the value of the local clock so that the clock gains or loses the specified amount of time.
-c Adjusts the local clock continuously. Adjustments specified with the switch should be on the order of
microseconds, and are added or subtracted from the local clock in small stages. This type of adjustment
avoids large instantaneous jumps and guarantees that the graph of local clock time versus real time remains
continuous.
The following example increments the local clock continuously by 500 microseconds: /etc/timedc incr -c 500
-d Adjusts the local clock instantaneously. Adjustments specified with the switch should be on the order of
seconds, and are added or subtracted from the local clock at once. The graph of local clock time versus real
time is discontinuous.
The following example decrements the local clock discontinuously by five minutes and two seconds: /etc/timedc
decr -d 5:2
