NTPTIME(8)              FreeBSD System Manager's Manual             NTPTIME(8)

NAME
     ntptime - read kernel time variables

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

DESCRIPTION
     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
     displays 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.

     -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.
