NAME

ntptime - 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.
