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
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.
