Current behaviour
When students are attempting a quiz with a certain quiz duration (e.g. 60 min) and meanwhile quiz duration is changed (e.g. to 70 min) this change is not reflected in the attempts of each student unless the student clicks on "next" or onto another question. If there is no user interaction the quiz closes after 60 min, the change in quiz duration is not passed to the single attempt.

Expected behaviour
Once the quiz duration is extended this information is passed from quiz settings to each attempt (also those currently running) immediately and withouth user interaction (means, without clicking on "next" or another question).

How to reproduce

1. Create a quiz with an essay question and restrict duration to 10min.
2. Write the quiz as a student. Keep wirting once in a while during the 10min.
3. After 5min of quiz duration passed, alter quiz duration to 15min.
4. Keep writing once in a while into the question but do not click on another question or on the next button (Suppose you urgently want to finish this one question and have already finished all others)

Use case
We use the Moodle quiz for exams. Sometimes these exams enclose long essay questions e.g. writing an analysis of one's teaching practice or programming code in an external software. When students run out of time lecturers sometimes decide to give them some extra time. This is done by quiz duration because it affects all students.

Note
The same problem exists when granting extended time duration for one student only using "Quiz administration > user overrides"
