Default Time for Course Start/End Date

Community Novice

Two questions:

1. Why is it necessary to change a course start/end date in Settings twice? I have to click Settings, change these dates, then click on Section at the top of Settings and then click "Edit Section" to do the same date modification.

2. When I do the first date change in Settings, why is the default time 12:00am? Canvas automatically chooses this time as its default, then tells you "Course participation is set to expire at midnight, so the previous day is the last day this course will be active." Okay, then why make 12:00am the default time if it means the date I choose will not actually be the date the course starts/ends?
