They do. That is why the time zones are already about 7.5 degrees to the west of where they should be as I’ve pointed out a couple times already.
That’s what I grew up with, too, and what I have now. We just get up from dinner if the doorbell rings. And lots of houses run out of candy or energy, and turn off their lights by 8:30 or so, so it’s not like people are staying up late for trick-or-treaters.
Hmmm. I hadn’t thought about that. I would be Greenwich Mean Time. But it would just be 6.5 hours. All the time.
