Say you changed business hours from 9 to 5 and made them 8 to 4. You would have to change your signwriting. In some cases reprogramme your security, computer and phone systems. You would have to change your public transport system timetables to cope with the earlier peak hour. The traffic light systems would have to be reprogrammed to suit.
