Comment 7 for bug 1818912

I just performed the same test I presented in my initial report on a system running 3.4.2. Same behavior happened. I picked a day that only had 12 circulations due.

Chose a library that is always closed Sundays, (Hours set to Closed in the Organizational Unit).
Added a single-day emergency closing for a specific Saturday.
Noted that the items due on that Saturday were updated to Sunday at 11:59 PM instead of the next open day - Monday.
