.SH NAME
\f\*[B-Font]calc_tickadj\fP
\- Calculates optimal value for tick given ntp drift file.
.SH SYNOPSIS
\f\*[B-Font]calc_tickadj\fP
.\" Mixture of short (flag) options and long options
[\f\*[B-Font]\-flags\f[]]
[\f\*[B-Font]\-flag\f[] [\f\*[I-Font]value\f[]]]
[\f\*[B-Font]\-\-option-name\f[][[=| ]\f\*[I-Font]value\f[]]]
.sp \n(Ppu
.ne 2
All arguments must be options.
.sp \n(Ppu
.ne 2
.SH DESCRIPTION
The \fBcalc_tickadj\fP 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.
.sp
The example output of
.br
.in +4
.nf
$ ./calc_tickadj
81.699 (drift)
9999 usec; 9999779 nsec
$ cat /etc/ntp/drift
-23.159
.in -4
.fi
.sp
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.
.sp
If 'tick' on that box is 10,000,000 then by setting it to 9999779 the drift
value will be somewhere around 0.0.
.sp
\fBcalc_tickadj\fP tries to determine the the tick value by using
\fBtickadj\fP program from ntp package. If this doesn't work you can specify
current tick manually on command line.
.SH "OPTIONS"
.TP
.NOP \f\*[B-Font]\-d\f[] \f\*[I-Font]string\f[], \f\*[B-Font]\-\-drift\-file\f[]=\f\*[I-Font]string\f[]
Ntp drift file to use.
The default
\f\*[I-Font]string\f[]
for this option is:
.ti +4
/etc/ntp/drift
.sp
Use the specified drift file for calculations
.TP
.NOP \f\*[B-Font]\-t\f[] \f\*[I-Font]number\f[], \f\*[B-Font]\-\-tick\f[]=\f\*[I-Font]number\f[]
Tick value of this host.
This option takes an integer number as its argument.
.sp
The current tick which to adjustment will be calculated
.TP
.NOP \f\*[B-Font]\-\&?\f[], \f\*[B-Font]\-\-help\f[]
Display usage information and exit.
.TP
.NOP \f\*[B-Font]\-\&!\f[], \f\*[B-Font]\-\-more-help\f[]
Pass the extended usage information through a pager.
.TP
.NOP \f\*[B-Font]\-v\f[] [{\f\*[I-Font]v|c|n\f[] \f\*[B-Font]\-\-version\f[] [{\f\*[I-Font]v|c|n\f[]}]}]
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.
.PP
.SH "EXIT STATUS"
One of the following exit values will be returned:
.TP
.NOP 0 " (EXIT_SUCCESS)"
Successful program execution.
.TP
.NOP 1 " (EXIT_FAILURE)"
The operation failed or the command syntax was not valid.
.TP
.NOP 70 " (EX_SOFTWARE)"
libopts had an internal operational error. Please report
it to autogen-users@lists.sourceforge.net. Thank you.
