The rules around timing of when assignments are delivered to students are:
- assignments become 'available' at 7 am on the start date, if an assignment was created before 7 am that day (including on an earlier date)
- assignments become available immediately on the start date if they are assigned after 7 am on the start date
- assignments are due at midnight on the end date
- assignments are created and managed in the context of the timezone of the computer they were created on.
