Rules are rules. As a CS student many years ago we had a 10am deadline for all work - I missed it once by less than 60 seconds. The punishment was always 20% of your mark deducted immediatly, with no excusses. A great learning experience at an impressionable age, so now in my professional life I've never missed a deadline though my own fault.
