You haven't taken into account the difference between mean solar time and apparent solar time. The system you describe is essentially the old local mean time https://en.wikipedia.org/wiki/Local_mean_time.

What is wrong with standard time?

People who play golf or engage in other outdoor activities like to maximize the amount of daylight hours after work. Instead of adjusting their work hours they have society and the government adjust the clock for everyone. Ideally the clock would be left alone but not everyone's employer is willing to allow for shifting one's work hours. Also schools aren't willing to seasonally adjust their hours so parents who want to maximize afternoon and evening daylight hours desire clock shifting.

DST was introduced in most countries during WW1 and/or WW2, to save fuel [1].

It _might_ be the case that golfers are the ones arguing to keep DST now, I havn't really noticed.

Believe golf is usually played at dawn, which always kept it out of my purview.

Completely depends. Different people have different preferences. Different locations have different weather benefits for time of day. When I played golf I played during twilight almost exclusively.

This is only when it involves dueling with one's opponent

Depends on your location I guess. Sun sets at 4:20 in the winter in Seattle under standard. So if we had to choose just one, I think many people would rather push that to 5:20.

But do you want a 9 AM sunrise?

I'm stuck at the office either way. Give me the evening daylight so I can enjoy my off-work time.

As someone who lives in Seattle: I genuinely don't care what time the sun rises.

Since I work from home it doesn't bother me anymore. But I used to hate commuting before the sun rose.

I think I'd prefer a 9 AM sunrise in the winter over the 4:11 AM sunrise that we'd currently be having if we were on standard time in the summer.

Absolutely. I'd pick DST just to avoid this alone.

Sounds good!

We could make that work with the tech we have these days. For example, meeting people at point A from points B and C, agree upon a time, then use google maps to tell you when to depart to arrive at point A at the agreed upon time.
