NTPTIME(8)

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. 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.
