Given that the sun rose at 10 am approximately 0 times this year [1] I guess the people in Urumql were ecstatic. Also note that the sunrise time varied by about 3h over the course of the year so how many times do you want to change the clocks?
Of course to your actual point and everybody else that brings that same one up. You do not need to wake up at 8am every day ... If the sun actually rises at 1400 then feel free to start your day at 1500. I'm not sure what why people keep arguing as-if they can't figure out a time besides 8am to wake up; look at the world around you, so many people wake up at wildly different times in a timezone.
