No, the more I think about this, PROGRAMMERS will HATE this.
I genuinely dont care if we pickstandard time” or “savings time” … i just want my year-round circadian rhythm to not get fucked up twice a year - it takes me so long to get used to the new one and then it gets rug pulled again.
You would wreak unmeasurable havoc across the target country.
I fully acknowledge that there would be some major disadvantages and challenges, but they mostly strike me as logistical and engineering challenges, rather than technological limitations. My car, which is not connected to the internet, knows when it's been a day, because it gives me time in AM and PM. There's no reason it couldn't count days and automatically adjust time based on this. Same for thermostats, microwaves, ovens, TVs, etc.
