Why not 2 Timezones for US?
twitter.comTwitter refuses to anonymously let me read tweets, so I don't know what the arguments are, but multiple studies show that the further west you live within a time zone, the shorter your lifespan. Causes include an increase in cancer rates (https://aacrjournals.org/cebp/article/26/8/1306/283057/Longi...) and suicide (https://www.sciencedirect.com/science/article/abs/pii/S01650...).
We'd be better of having time zones every half hour, instead of every hour.
Alaska and Hawaii are also in the US. Perhaps better one for the continent based on high noon at Chicago, and get rid of daylight saving time.
So we would emulate the mainland Chinese and the Russian railways ?
It would be coincidental, but it all works out on a human scale, if only we had better trains. It would not make us communists, which by the way, Vietnam is building a high-speed rail link between their two biggest cities for a fraction of the price of California High-Speed Rail.
1 would be great. I favor New York winter time, in case we join South America in the future.
