<code>ntptime</code> - read kernel time variables

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. It reads and displays time-related kernel variables using the ntp_gettime() system call. A similar display can be obtained using the xntpdc 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.
