Second Intrinsic (subroutine)
.............................

     CALL Second(SECONDS)

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

Intrinsic groups: `unix'.

Description:

   Returns the process's runtime in seconds in SECONDS--the same value
as the UNIX function `etime' returns.

   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.

   This routine is known from Cray Fortran.  Note: CPU_Time Intrinsic,
for a standard equivalent.
