NAME

ntptime — read kernel time variables

SYNOPSIS

ntptime

[-chr] [-e est_error] [-f frequency] [-m max_error] [-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.

OPTIONS

-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.
