Reno, NV (39.530895, -119.814972) is west of San Diego, CA (32.71533, -117.15726). It isn't Nevada picking the wrong time zone.

If we're going to make a big change why not US Standard Time? China runs a single national time zone China Standard Time.

Yeah, it looks like various interests simply lobby for the time convenient to their own industry. Nevada is indeed more into Pacific than Mountain -- in fact, the whole of Nevada and some part of Utah should be within the Pacific if we're looking for the best alignment.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6692659/ -- and specifically https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6692659/figure/... -- provides maps which show the best longitude-based alignment for the timezones, and Nevada is entirely within the Pacific portion.

Isn't the US a bit too wide to have a single timezone? They've tried it in Russia in 2010s, to skip a few "extra" timezones, because 11 total timezones is quite a bunch as-is, but, apparently, the folks weren't all too happy about it, and the change was reverted several years later.
