       ntptime - read kernel time variables


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


       This program is useful only with special kernels  described  in  the  A
       Kernel  Model  for  Precision  Timekeeping  page. It reads and displays
       time-related kernel variables using the ntp_gettime()  system  call.  A
       similar  display  can  be obtained using the ntpdc program and kerninfo


       -c     Display the execution time of ntptime itself.

       -e est_error
              Specify estimated error, in microseconds.

       -f frequency
              Specify frequency offset, in parts per million.

       -h     Display help information.

       -m max_error
              Specify max possible errors, in microseconds.

       -o offset
              Specify clock offset, in microseconds.

       -r     Display Unix and NTP times in raw format.

       -s status
              Specify clock status. Better know what you are doing.

       -t time_constant
              Specify time constant, an integer in the range 0-10.
