This program is useful only with special kernels described in the A Kernel Model for Precision Timekeeping 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.
