There's still a lot of room there for issues, even if every meeting actually does end on time. Say on person or team takes that to always have meetings end at :25 or :55, another always ends at :35 or :05, and another team say :15 and :45 for any meeting end times. In my experience meetings seem to fall into common durations, always in intervals of 15 minutes but most common at 30 minutes or an hour. I'd go even more strict on times and say meetings must start at :00 or :30, and always end by :25 or :55. That enforces a 5 minute window and standardizes start times without preventing longer meetings that need to run for 90 minutes or longer.
