What exactly is the relationship between the Date and Limit Duration fields on the Quiz Submission View, View Restrictions? Do they work together or does one cancel the other out?
 

For instance, is it possible to open up access to an additional view 24-hours after the end date and permit access for a 10-hour period?

 

If View Restrictions Date and Limited Duration are mutually exclusive or conflictual, it would be clearer to put them under a radio button grouping.
