ount,'' and ``mod 800 count.'' The values in the first and second
   fields normally range from zero to the modulus of the field, minus 1.
   The range of the third field is from 1 to 800. The ``offset'' for the
   third field is 1, so values in this field normally range from 1 to 800
   rather than from 0 to 799; values above 800 are allowed and treated as
   described above.

   clocks can represent (65535:59:800) is approximately
