DTime(TArray)

DTime: `REAL(KIND=1)`

function.

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

; DIMENSION(2); INTENT(OUT).

Intrinsic groups: `badu77`

.

Description:

Initially, 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)`

.

Subsequent invocations of `DTIME()`

return values accumulated since the
previous invocation.

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.

Due to the side effects performed by this intrinsic, the function form is not recommended.
