It's a current WIP idea for the spec: https://github.com/tc39/proposal-temporal/pull/700

Figuring out a name is still part of the ongoing discussion, so this specific case of `LocalDateTime` isn't a huge deal, and I might have misrepresented things slightly in my original comment, sorry! But I do think the overall point still stands - that it might be best to just use the same names and terminology as Java does.
