Thanks for the reply.
It turns out that the declared function of time limitation in the passage of the task is absolutely useless.
Imagine the situation when the user passes the task of 20 questions and does not fit into the limit:
A result message is displayed depending on the points scored on the previously scaled result scale.
I would not understand why I went through a paid test of 20 questions, but on the 5th question the result is already output, and the result is poor (it is clear that only 5 points out of the possible 20 are taken into account).
In any case, this is a clear flaw in the developers of the component...
