       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 command.


       -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.
