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. Gener-
     ally, 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 pack-
     age. 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 no-
             tice.

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.

             libopts had an internal operational error.  Please report it to auto-
             gen-users AT lists.net.  Thank you.
