Sadly, this isn't really right. Humanity settled on solar time. For somewhat obvious reasons.

Alas, I don't see my preferred method of changing the clock by 10 minutes every month taking hold. Basically ever. :D

I also don't think this is nearly as important for places that are not further away from the equator. If you are on the equator, you are almost certainly fine with no change throughout the year.

That method wont work, that is a too large change that happens to seldom. What you want is a leap second every hour for five months to switch between standard and daylight savings time and back, with a month of constant time around each solstice. That gives you a smooth transition without perceptible discontinuities.
