There was a problem hiding this comment.
I wonder if we could extract a generic function typed on the timestamp and duration types, this would avoid the duplication?

I think this is fine, we don't provide arithmetic between different integer precisions either - I think the responsibility is on the query engine to add type coercion logic where necessary 👍 |
