DESCRIPTION
The
ntptime utility is useful only with special kernels described in the “A Kernel Model for Precision Timekeeping” 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
ntptime 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.
