CPU_Time Intrinsic
..................

     CALL CPU_Time(SECONDS)

SECONDS: `REAL'; scalar; INTENT(OUT).

Intrinsic groups: `f90'.

Description:

   Returns in SECONDS the current value of the system time.  This
implementation of the Fortran 95 intrinsic is just an alias for
`second' Note: Second Intrinsic (subroutine).

   On some systems, the underlying timings are represented using types
with sufficiently small limits that overflows (wraparounds) are
possible, such as 32-bit types.  Therefore, the values returned by this
intrinsic might be, or become, negative, or numerically less than
previous values, during a single run of the compiled program.
