No we don’t. We change timezone, not the time within that timezone.

The former is government mandated and our clocks are changed. The latter is governed by ourselves and we have to change all schedules to reflect a new time 7am (etc) instead of 8am while the clocks remain the same.

The devil is in the detail.

Whether you change timezone or change time is largely inconsequential. The effect is nearly the same, and it's not like it hasn't happened several times in the past. Society progresses. In an increasingly 24-hour world, it isn't going to matter. And in a society that has increasing concern about the health of its citizens, what the clock says won't matter as much as what our bodies say.

While that’s true it’s also tangential to what was being discussed

I don't see a practical difference. Do you mean we have to work to remove the time skip?
