[-m

[-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.

itself.

est_error
- Specify estimated error, in microseconds.
-
-
- -f
frequency
- Specify frequency offset, in parts per million.
-
-
- -h

- -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
