The interface on the grading page talks about the submittion time, for example “This submission was submitted Sun, Mar 13, 2022 04:38:16. Deadline passed.” However, in this case the student last saved before the deadline (namely, at Fri, Mar 11, 2022 23:46:19), and therefore no penalty is calculated for the student. The interface should make this more clear by talking about the last save time and not the submission time.
