My team does this, most scheduled meetings are scheduled 5m/10m after the hour. Meetings usually end at the hour or before. Our calendar defaults to start/end on the hour so sometimes one-off meetings will start/end on the hour but those are usually 2-3 people and focused on solving some problem so they don't usually last the full time anyway.

For the larger scheduled meetings, if they drag over the hour because of some conversation our culture is that people leave/drop if they're not interested.
