Let’s continue the discussion on UT vs UTC over in [Universal Time vs UTC Time in Dates](https://discourse.julialang.org/t/universal-time-vs-utc-time-in-dates/103204) and try to keep this topic on the higher precision arithmetic. My split wasn’t perfect here, but I tried to preserve as much as I could. In doing so, I unfortunately ran into some Discourse bugs, which placed some posts completely out of order. Please ping me if you see anything that’s still out-of-place or nonsensical in its (possibly new) context, but I _think_ I got it now.
