Clock is a social contract. China has just one time zone and it seems to work fine.
There's a noticeable increase in sleep disorders and related conditions in the far west of the single time zone [0]. I think when it's on the order of a single hour's shift for daylight savings the effects are pretty negligible but they are measurable.
The thing about DST is it makes every scheduled event move, all at the same time.
It shifts my contracted start time at work, my first meeting, when places start serving lunch, when my kid needs to get to ballet class, when my sportsball club meets, and when the supermarket closes. All at once.
Lawmakers changing the time shown on clocks is, I think, a lot easier than society changing the social contract.
