ntptime - read kernel time variables


See Also


ntptime [-chr] [-e est_error] [-f frequency] [-m max_error] [-o offset] [-s status] [-t time_constant]


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.
