            "content": "This program is useful only with special kernels described in the A Kernel Model  for  Preci‐\nsion Timekeeping page. It reads and displays time-related kernel variables using the ntpget‐\ntime() system call. A similar display can be obtained using the ntpdc  program  and  kerninfo\ncommand.\n",
