ntptime ā€” read and set 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 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 help information.

-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

Specify clock status. Better know what you are doing.

-t time_constant

Specify time constant, an integer in the range 0-10.
