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.
