- read kernel time variables
SYNOPSIS
[-chr

[-e est_error
]
[-f frequency
]
[-m max_error
]
[-o offset
]
[-s status
]
[-t time_constant
]
DESCRIPTION
The
utility is useful only with special kernels
described in the
Qo A Kernel Model for Precision Timekeeping
Qc page
(available as part of the HTML documentation
provided in
/usr/share/doc/ntp )
It reads and displays time-related kernel variables
using the
gettime ();
and
adjtime(2)
system calls if available.
A similar display can be obtained using the
ntpdc(8)
program's
kerninfo
command.
The following options are available:
-c
Display the execution time of
itself.
-e est_error
Specify estimated error, in microseconds.
-f frequency
Specify frequency offset, in parts per million.
-h
Display help information.
-l
Specify the leap bits as a code from 0 to 3.
-m max_error
Specify max possible errors, in microseconds.
-o offset
Specify clock offset, in microseconds.
-r
Display Unix and NTP times in raw format.
-s status
-t time_constant
Specify time constant, an integer in the range 0-4.
