I think you missed some context. They're talking about the differences between sticking with summer time vs sticking with winter time but moving things by an hour (so a 9-5 job would be 8-4). In both cases things would happen at the same solar time. Basically the convo was: A: People want to change their clocks to summer time instead of changing their personal schedule B: They don't want to change their personal time but rather society's time A: They could just change society's schedule, it's just as easy. C: Nah, you'd have to change a lot of things, signs, timetables, etc...
