NAME
       ntptime - read and set kernel time variables

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

DESCRIPTION
       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.

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 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.

       -M      Switch to microsecond mode.

       -N      Switch to nanosecond mode.

       -T tai_offset
	       Set TAI offset.
