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.
-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.
