Late submission

I had a submission deadline using Turnitin at 23:59. Due to some technical issues with my computer I had submitted it at around 23:55 but the time due to the issues the time that is showing as submitted is 23:59 both on the blackboard as well as on the turnitin digital receipt. I am worried that would an exactly 23:59 submission on that deadline would be labelled as late. I know that I was already late to submit it at 23:55 but I had no other choice. Please if anyone knows anything and can answer this question it would be of great help.
