I'd rather have a 5-minute break built-in for everyone by starting 5-past and actually enforce meeting end-times. Behaviors would change if people knew they had 25 or 55 minutes for a meeting and that folks would just leave when the time is up.
Seen from within the meeting, it does not really matter if you start 5 minutes late or end 5 minutes early.
I think the point is to reduce meeting time from 60 minutes to 55 or even 50 and be firm about it. People need to expect to start and end on time; giving them a natural break between helps make this happen even for people whose job requires them to be in back-to-back meetings.
Personally, I think starting on the hour (or half-hour, etc) and ending "early" is better, because it tends to sync well with the calendars of external folks.
But in the end, moving start or end time is only part of the solution. This is a time-management problem, and in addition to constraining the available time, it also needs proper management of the available time within the meeting.
