Nice 👍

Presume it is already on your radar, but following this I think extract_component_from_datetime_array can be simplified to use PrimitiveArray::unary

array: A,
dt: &DataType,
) -> Result<Int32Array>
fn month_internal<T>(array: &PrimitiveArray<T>) -> Result<Int32Array>

It occurs to me that these _internal methods are no longer necessary as they now have the same signature as the non _internal methods

name: &str,
op: F,
) -> Result<Int32Array>
fn time_fraction_dyn<F>(array: &dyn Array, name: &str, op: F) -> Result<ArrayRef>

I wonder if more of the kernels could be implemented using this, possibly something for a future PR

Yea, I will do some cleanup later for this and probably for #3046 (comment).
