Hi there, @jts0047 ...
This is interesting and a little strange. I've never heard of a situation like you've described before. Just for clarification, when you click on a link in your course to start taking a quiz, you'll see a screen that has some initial information about the quiz...such as this:

Has your instructor set a time limit on your quiz? In my example, there is no time limit set.
Another thing to check (and I'm not even sure if this would help or not) would be your own time zone settings for your Canvas account. How do I set a time zone in my user account as a student?
If you could check on these things in your Canvas account to see if there is any improvement, that would be great. Other than those things, I cannot think of anything else to try at the moment other than to reach out to Canvas Support.
Looking forward to hearing back from you soon! Take care, stay safe, and be well.
