Calculates optimal value for tick given ntp drift
All arguments must be options.
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
9999 usec; 9999779 nsec
$ cat /etc/ntp/drift
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.
tries to determine the the tick value by using
program from ntp package. If this doesn't work you can specify
current tick manually on command line.
- Ntp drift file to use. The default
string for this option is:
Use the specified drift file for calculations
- Tick value of this host. This option takes an integer
number as its argument.
The current tick which to adjustment will be calculated
- Display usage information and exit.
- Pass the extended usage information through a pager.
- 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.
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
- 70 (EX_SOFTWARE)
- libopts had an internal operational error. Please report it
to firstname.lastname@example.org. Thank you.
