I had a course end on July 27, 2017. Assignments were given a close date of July 27, 2017.
However I set the course end date to Oct 31, 2017 to handle students with incompletes.
In cleaning up the queues of assignments for the final grades, (this is an area on the right side of the home screen, under the 'new announcement' and above the 'coming up' sections). I checked the area August 1 and there were no assignments listed to be graded.
Today, I noticed several assignments in this area that students submitted after the course ended on July 27, 2017. They had a timestamp submission of July 27, 2017, 11:59 pm. There were several students with this timestamp.
Contrary to the timestamp, I believe that these items were submitted after August 1, when I finished the queue of to-be-graded assignments. I am asking whether the timestamp comes from where the students may have left Canvas opened on the particular assignments, did not exit canvas, and submitted the assignment after July 27.
I have searched for whether this is the case but not successfully.
Could anyone clear this up?
