NAME

       calc_tickadj - Calculates optimal value for tick given ntp drift file.

SYNOPSIS

       calc_tickadj [-flags] [-flag [value]] [--option-name[[=| ]value]]

       All arguments must be options.

DESCRIPTION

       The  calc_tickadj script uses provided ntp drift file to generate optimal tick value. Generally, ntpd can
       do better job if the drift value is the smallest possible number.

       The example output of
           $ ./calc_tickadj
           81.699 (drift)
           9999 usec; 9999779 nsec
           $ cat /etc/ntp/drift
           -23.159

       means the following. If tick on that box is 10,000, by making the value 9999 we'll shift the box from its
       current drift of -23.159 to a drift of 81.699, and in doing so we'll speed the clock up  a  little  every
       second instead of slowing the clock down a little.

       If  'tick'  on  that  box  is  10,000,000 then by setting it to 9999779 the drift value will be somewhere
       around 0.0.

       calc_tickadj tries to determine the the tick value by using tickadj program from  ntp  package.  If  this
       doesn't work you can specify current tick manually on command line.

OPTIONS

       -d string, --drift-file=string Ntp drift file to use.  The default string for this option is:
            /etc/ntp/drift

       Use the specified drift file for calculations

       -t number, --tick=number Tick value of this host.  This option takes an integer number as its argument.

       The current tick which to adjustment will be calculated

       -?, --help Display usage information and exit.

       -!, --more-help Pass the extended usage information through a pager.

       -v [{v|c|n --version [{v|c|n}]}] Output version of program and exit.  The default mode is `v', a simple
       version.  The `c' mode will print copyright information and `n' will print the full copyright notice.

       EXIT STATUS
              One of the following exit values will be returned:

       0  (EXIT_SUCCESS) Successful program execution.

       1  (EXIT_FAILURE) The operation failed or the command syntax was not valid.

       70  (EX_SOFTWARE) libopts had an internal operational error.  Please report it to autogen-
       users@lists.sourceforge.net.  Thank you.
