stevomitric opened a new pull request, #56207: URL: https://github.com/apache/spark/pull/56207
### What changes were proposed in this pull request? Implement `Ordering` for `TimestampNTZNanosType(p)` and `TimestampLTZNanosType(p)`, both in the interpreted path and the codegen path. ### Why are the changes needed? Without ordering, SQL operators that need a total order on the type (`ORDER BY`, sort-merge join, sort-based `GROUP BY`, `DISTINCT`) cannot execute against nanos-precision columns. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? New UT in this PR. ### Was this patch authored or co-authored using generative AI tooling?
