narrowing down to the problem point: we can drill down `Arrow.Table(Arrow.tobuffer(t))` to a call to `toarrowvector(t.x)`, which then results in an invocation of `arrowvector`: xref https://github.com/apache/arrow-julia/blob/0c4793871d911e185cb6a9603e577a1f52f52a22/src/arraytypes/arraytypes.jl#L52-L69 I think the bit where things start to derail is `ToArrow(x)`, which results in: ```jl julia> x = Arrow.ToArrow(t.x) 1-element ArrowTypes.ToArrow{Missing, Vector{Union{Missing, ZonedDateTime}}}: missing julia> eltype(x) Missing ``` So `S` ends up being `Missing`, the whole operation starts flowing down the `NullKind` path for serialization purposes, but `T` is `ZonedDateTime` and so `meta` reflects `ZonedDateTime` it seems to me like `ToArrow` should probably be returning something different here.
