CALL ETime(TArray,Result)

`TArray`: `REAL(KIND=1)`

; DIMENSION(2); INTENT(OUT).

`Result`: `REAL(KIND=1)`

; scalar; INTENT(OUT).

Intrinsic groups: `unix`

.

Description:

Return the number of seconds of runtime
since the start of the process's execution
in `Result`,
and the user and system components of this in `TArray``(1)`

and `TArray``(2)`

respectively.
The value of `Result` 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.

Some non-GNU implementations of Fortran provide this intrinsic as only a function, not as a subroutine.
