> This is very similar to CALCITE-5424, which only applied to literals (e.g.
> {{TIMESTAMP '2023-10-17 12:00:00'}}). We need a similar solution for [the
> {{DateTimeTypeName}}
> construction|https://github.com/apache/calcite/blob/6f79436c178beec639e559d9152c237bbf8ec3e8/core/src/main/codegen/templates/Parser.jj#L6019]
> which is used in other contexts (e.g. {{CAST('2023-10-17 12:00:00' AS
> TIMESTAMP)}}). Seems like we can use a very similar approach: introduce a
> {{SqlUnknownTypeNameSpec}} that's resolved during validation.
