ntptime - read kernel time variables
ntptime [ -chr ] [ -e est_error ] [ -f frequency ] [ -m max_error ] [ -o offset ] [ -s status ] [ -t time_constant ]
This program is useful only with special kernels described in theA Kernel Model for Precision Timekeepingpage. 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.
