NTPTIME(8)						    BSD 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

     This program is useful only with special kernels described in the A Kernel Model for Precision Timekeeping page in
     /usr/share/doc/html/ntp/kern.html.  It reads and displays time-related kernel variables using the ntp_gettime(2) system call.  A similar dis-
     play can be obtained using the ntpdc program and kerninfo command.

OPTIONS

     -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 times in Unix timeval format. Default is NTP format.

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

     -m max_error
	     Display help information.

     -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 0-4.
