The universities thing is interesting, I've attended and seen several in the Pacific Northwest, USA. They universally ran at exact times, and ended with a buffer, such as 10 minutes until the next timeslot. e.g. 10:00 am - 11:50 am for a 'two hour' lecture, 3:00 pm - 4:20 pm for a twice a week '3 hours per week' lecture and similar. They would typically start on time or shortly after, and tardiness was frowned upon.
Hilariously, when classes were right after one another this sometimes meant down the hall or the building across the street and plenty of leisure time, or it could mean corner to corner on a huge campus and having to leave early, arrive late, or run. In this sense the buffer times didn't solve the problem either.
