You've misread the parent. They are saying that on a given day, the number of hours of sunlight is the same whether it's daylight or standard time. The only thing that changes is when in the day the sun is shining.

Oh, I see.

TheCoelacanth was arguing about summer vs. winter so that's the thread I was following in my mind.

I believe he meant you get n hours of sunlight in the summer, regardless of whether you arbitrarily decide to call it 6 AM or 7 AM when the sun rises.

The amount of sunlight stays the same, but you have to rename the phenomenon to "1am sun" or whatever

I grew up in the land of the midnight sun. I am not sure what point you are trying to make. People really don't complain much about it being light until late. It is much more common to hear people complain about the sun setting sooner as fall approaches.

The above poster is referring to the amount of sunlight between a savings and standard time basis - not between summer and winter.
