If the sun is at it’s relative peak at noon, why does it take so much longer to set than it does to rise for at least half of the year?

The closer you are to the date of the summer solstice, it seems to gradually take up to 10 hours for the sun to set. Yet, the sun doesn’t begin to rise at 2am. Why is that?

Many places have daylight savings or summer time where they shift the clock an hour.. so afternoon is longer at the expense of evening.

The world is split in 24 time zones, each one being an hour of rotation or 15 degrees wide. This is not accidental.

Early navigation using an accurate clock will show that if a clock is set at noon at the British naval observatory, (prime meridian 0 degrees) if you travel any where on earth, at “Solar noon” the clock will show a “time” that is the “amount” of East/west rotation from the prime meridian.

So at solar noon in Chicago the clock might read around 6:48am ( around 87 degrees west)

In Paris it would read something like 12:05pm (2 deg east)

In Tokyo it would read 9:20pm. (140 degrees east )
( my math might not be exact)
