Functional Return 

count                 32-bit signed integer (assigned functional return) 

                      The actual millisecond count since the midnight
                      preceding the last system coldload.

Operation Notes 

The resolution of the system timer is one millisecond; readings taken
within a one-millisecond period can be identical.  The system timer is
reset to zero every 24-days at 12:00 midnight.  If using the TIMER
intrinsic to compute elapsed time, correct for this condition by:

   *   Subtracting the current count from the previous count.

   *   If the result is negative, add 2,073,600,000 (number of
       milliseconds in 24 days).
