I can understand not exactly lining up, but considering how large the country is and how Beijing is so far east it seems like people in the west would have the sun rise at 2:00 or the sunsetting at 14:00. I don't know this for certain I'm just curious how not lined up it can get at the most extremes.

As long I am not working the same hours as people in the far east of China, I would not really care about what the clock reads at sunset: I'd just get up around sunrise at n o'clock, spend my hours at work and finally go to bed at m o clock. The only difference between n=6, m=22 or n=22,m=14 is habituation. We're used to the former.

But it would definitely screw up cultural references, e.g.: a "5pm tea" then can only be understood with a broader cultural context: "UK, 5pm is late in the 2nd half of the working day for them".
