NTPTIME(8) System Manager's Manual 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 The ntptime utility is useful only with special kernels described in the "A Kernel Model for Precision Timekeeping" page (available as part of the HTML documentation provided in /usr/share/doc/ntp). It reads and displays time- related kernel variables using the gettime() and adjtime(2) system calls if available. A similar display can be obtained using the ntpdc(8) program's kerninfo command. The following options are available: -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 -t time_constant Specify time constant, an integer in the range 0-4.
