Timer in questionnaire

Is it possible use a timer in macros?
I need to force interviewer to wait sometime before going to next question.
I used

(null != new System.Threading.Timer((state) => {
    v_timeout = true;
    } , null, 10000, -1)
    )

Variable is using forbidden type

Thanks.

@sergiy Is there a solution to introduce a delay?

Thanks.

You can’t.

In Survey Solutions each question is either available (enabled) or not. And any available question may be answered at any time. THERE IS NO “CURRENT” or “NEXT” QUESTION.

Why is this needed/required/desirable?

Is this somehow related to " In have a requirement to show 2 images for 30 seconds each, before displaying the question. Is this possible in survey solutions? How would I achieve this? "?
