Example:

Task set to recur upon closed "1 day after" at 9pm.

WHAT I EXPECT TO HAPPEN

Regardless of time of day, I expect that if I mark it closed on Monday, the due date/time will change to TUESDAY at 9pm

WHAT ACTUALLY HAPPENS

If I mark it closed before 9pm, the due date and time do not change. e.g., if I mark it closed on 7pm Monday, it then shows due 9pm Monday.
