March 29, 2000 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 page in ```/usr/share/doc/html/ntp/kern.html`. It reads and displays time-related kernel variables using the ntp_gettime(2) 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 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.
