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
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 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 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.
