I agree with that, but it is my understanding that Noda's  LocalDatetime
concept most closely matches our "naive datetime" concept.

According to Noda documentation, LocalDatetime is

"A date and time in a particular calendar system. A LocalDateTime value
does not represent an instant on the time line, because it has no
associated time zone: "November 12th 2009 7pm, ISO calendar" occurred at
different instants for different people around the world." [1]

Since it "has no associated time zone," it "does *not* always mean local
time" even thought it has "Local" in the name.
