LGTM, but could you add the newly supported types in https://arrow.apache.org/docs/cpp/compute.html#arithmetic-functions ?

I changed them to "Numeric/Temporal" to be consistent with other functions. This may be misleading though since only duration is supported.

Perhaps "Numeric/Duration" then?

Sure. Updated.

Thanks @js8544 , and sorry for the delay.
