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.
