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.
