yeah, it was a long (and painful) time coming, but i think the temporal api finally basically nailed it. you know a library is good when you learn something about how to think about the problem just from how the code/api is structured.

Relatedly, std::chrono isnt exactly a beauty, but it did get people thinking about time points and durations and clocks and which operations are valid ways to move among them. Stuff like this is good.
