   Accommodating new spacecraft clocks may involve no code changes to the
   SCLK subroutines whatsoever.
<P>
 
   If a new clock fits into the framework of clock type 1, then the clock
   can be accommodated simply by producing a new kernel file for that
   spacecraft clock. For the new clock, a new set of kernel variables
   corresponding to those described above, and those in the chapter
   ``SCLK01,'' could be added to an existing SCLK kernel file.
   Alternatively, an entirely ne
