   slightly more minimal MWE (note this also triggers the MethodError if you use `t1 = (; x = [[Nanosecond(1)]])`:
   
   ```jl
   julia> t1 = (; x = [(Nanosecond(1),)])
   (x = [(Nanosecond(1),)],)
   
   julia> t2 = Arrow.Table(Arrow.tobuffer(t1))
   Arrow.Table with 1 rows, 1 columns, and schema:
    :x  Tuple{Nanosecond}
   
   julia> Arrow.tobuffer(t2)
   ERROR: MethodError: no method matching arrowtype(::Arrow.FlatBuffers.Builder, ::Type{Nanosecond})
   ```
