     ntptime — read kernel time variables

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

     The ntptime utility is useful only with special kernels described in the
     "A Kernel Model for Precision Timekeeping" page (available as part of the
     HTML documentation provided in /usr/share/doc/ntp).  It reads and dis‐
     plays time-related kernel variables using the gettime() and adjtime(2)
     system calls if available.	 A similar display can be obtained using the
     ntpdc(8) program's kerninfo command.

     The following options are available:

     -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.

     -l	     Specify the leap bits as a code from 0 to 3.

     -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

     -t time_constant
	     Specify time constant, an integer in the range 0-4.
