Along with the new Honorlock integration, is there now a learner-friendly way to set the time allowed on a test to less than 24 hours? 

There is an option to set the time in increments of 1 hour at the test level, but for it to be enforced, you also have to check the option that locks the user out of the test forever if they accidentally close the tab. If you do not check this option, the user can pause the timer whenever they want by closing the test. The only way to get a timer that persists regardless of the test being open or closed is to set the duration at the course level, which has a minimum time of 1 day.

Honorlock sounds like it might be useful, but I’m not sure how it would play with the gap in timing functionality.
