NAME
     ntptime - Display Kernel Time Variables.

SYNOPSIS
     /usr/sbin/ntptime [-chr] [-e est_error] [-f frequency]
      [-m max_error] [-o offset] [-s status] [-t time_constant]

DESCRIPTION
     This program is used to display or set the kernel  variables
     used   by   NTP   as   described  in  the  documentation  at
     file:///usr/share/doc/ntp/kern.html entitled "A Kernel Model
     for   Precision  Timekeeping".  A  similar  display  can  be
     obtained using the ntpdc program and kerninfo  command.  The
     actual  meaning  of  these  variables is rather difficult to
     understand, but the ntptime program is primarily  useful  to
     determine  if  the variables are set at all or to clear them
     if they are.

OPTIONS
     -c   Display the time taken to call ntp_gettime (us)

     -e esterror
          Set the estimated error, in microseconds.

     -f frequency
          Set the frequency error (-500 ..  500),  in  parts  per
          million.

     -h   Display help information.

     -m maxerror
          Set the maximum possible error, in microseconds.

     -o offset
          Set the offset in microseconds.

     -r   Print the unix and NTP time raw

     -s status
          Set the status bits. Do not use this  unless  you  know
          what you are doing.

     -t timeconstant
          Set the log2 of PLL time constant, an  integer  in  the
          range 0-10.
