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.
