> [C++] Compute Function to return Year / Month / Day

>
> Right now the temporal compute functions include year / month / day as
> separate functions. AFAICT in the implementation these all internally create
> a struct containing year/month/day using the date library and then return
> only one of the components.
>
> From a pure efficiency perspective it might be best to just return all as one
> StructArray and allow the user to unpack the values. From a user perspective,
> I also typically want year / month / day to be bundled together, so one
> function call to get all three in one pass would be ideal
>
> This might be extendable down to the timestamp structure as well
