On further reflection I wonder whether we shouldn't just get rid of
"8.5.6. Internals", which is at best rather inappropriately placed.
A person reading this portion of the docs probably couldn't care less
whether we use Julian-date calculations internally. It might be
appropriate to mention that in appendix B.4, where there's an actual
explanation of what Julian dates are; but not here.
What I think we should have here is an externally-facing specification,
that is state that we follow the Gregorian calendar rules even for years
before Pope Gregory's edict, and then reference B.4 for more info.
