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.
