When we leave the office we swipe to street time, period. As we do a pivot on the street, we fill out the bottom of the 3996: begin travel to, end travel to, begin delivery, end delivery, begin travel from and end travel from. When we return to the office we swipe in to office time on our route (if we are a regular) or to the route of the last pivot we were doing. All other timekeeping work is done by management. No retro rings here.
