We really do not in the US when it's a matter of genuine controversy. Once in a long while something gets forced through if the status quo is just unsustainable or it's a core plank issue or something, but the system isn't designed to allow anyone hitting 51 to easily pass anything contentious. And that's with your implicit take that there is a 51-49, but that's the thing, it's not a dichotomy in the first place. It's more like 25/25/40/5/3/1/1. Plus this isn't some inherently critical issue, for most people it's at most a minor irritation twice per year. For some it's a minor enjoyable, "free sleep". And thus status quo rules :).
>People in the past had a very different time environment. I used to have 1 watch. Now I have a dozen different clocks in my apartment.
Indeed! Our clocks used to not have global sub-millisecond automatic time synchronization.
