ETime Intrinsic (function)

     ETime(TARRAY)

ETime: `REAL(KIND=1)' function.

TARRAY: `REAL(KIND=1)'; DIMENSION(2); INTENT(OUT).

Intrinsic groups: `unix'.

Description:

   Return the number of seconds of runtime since the start of the
process's execution as the function value, and the user and system
components of this in `TARRAY(1)' and `TARRAY(2)' respectively.  The
functions' value is equal to `TARRAY(1) + TARRAY(2)'.

   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.
