clock start
   (10:05:50 a.m. to 36350; 10:05:50 p.m. to 36350 + 12(60)(60) = 79550).
<P>
 
   When you pass a SCLK string to <a href="../cspice/scencd_c.html">scencd_c</a>, it is normally prefixed with a
   number indicating the partition in which the count falls. Sample SCLK
   strings for Voyager 2, including partition numbers, are given in an
   example program later in this document.
<P>
 
   The presence of the partition number is not always required. If it is
   missing, <a href="../cspice/scencd_c.h
