I guess maybe I didn't explain myself well. Swift is supposedly a cross platform language. This "protocol" unlike the specific clocks certainly seems like something you could equally well provide on say, Linux. But, it's documented as requiring (among others) iOS 16.0+ Maybe there's a separate view onto this documentation if you care about non-Apple platforms? Or maybe there's just an entirely different standard library for everybody else?
