In the situation you describe, I use the assignment settings to control the time the assignment is available. I use 3 days, but 12 hours can be set there as well. That can only be set using the three dot menu on the assignment tab.
For the students who get extra time on quizzes and exams (which in my case have time limits ranging from 10 to 90 minutes) our policy is generally that time and a half is a reasonable accommodation of extra time. What new quizzes does, that classic quizzes never did, is let me set a multiplier (1.5) that automatically adjusts every 10 minute quiz to 15 minutes, and every 90 minute exam to 135 minutes. All by adjusting one setting (from the pencil icon in the row of that student on the moderate tab of ANY quiz, select "time limit multiplier" and canvas does the rest for EVERY quiz.)
The tools in the moderate button only impact the current (or most recent for reopening) attempt, and so that makes them suited for fixing things that come up only on the one quiz, that you might use live moderation for. The tools on the moderate button still need some work to be effective, as I noted before. Since it does not actually add time to an ongoing attempt in your test, you might try:
- make sure the added time isn't trying to extend beyond the until date set in the assignment tab
- attempts that are "in progress" give you an option to conclude the attempt from the moderating tab try doing that, adding the time, and then clicking reopen
I have heard some who set a specific time for an exam, when they intend to monitor students live complain about the lack of updates on the moderating page. They want to keep it open for the hour of the exam (for example) and address any students who have not started, or who stop interacting with the quiz live. That is more monitoring then I intend to do, but you are not wrong that it is desired by some.
