Urumuqi actually delays store openings/closings (department stores open at 11AM, for example), so it isn't that bad. Beijing time in Beijing should be accurate, but without DST, the sun rises way too early in the morning. But even then the schedules are still fixed, just the Chinese enjoy their night life, so the sun setting at 6-7PM in the summer isn't really a big deal.

Our school schedules are set by weird rules involving when school bus capacity is available. But in general, 9AM is about when school starts (for my son's K-8, its 8AM here for K-5s), or summer camp session starts, or whatever. My schedule is so influenced by my kid these days, it happens to correspond to rush hour, which sucks, because everyone else's schedules are intertwined (so traffic).

I WFH and can definitely set my own work hours. Which is why its 12:30 AM and I still haven't gone to bed yet.
