stevomitric opened a new pull request, #58658: URL: https://github.com/apache/spark/pull/58658
### What changes were proposed in this pull request? `time_bucket(bucketSize, ts[, origin])` now accepts and returns nanosecond-precision timestamps (`TIMESTAMP_LTZ(p)` / `TIMESTAMP_NTZ(p)`, p ∈ [7, 9]), alongside the existing microsecond types. ### Why are the changes needed? Part of nanosecond-precision timestamp support (SPARK-56822). `time_bucket` previously rejected nanosecond timestamps at analysis. ### Does this PR introduce _any_ user-facing change? Yes, `time_bucket` now works on nanosecond-precision timestamp columns. ### How was this patch tested? New `DateExpressionsSuite` cases covering day-time and year-month buckets ### Was this patch authored or co-authored using generative AI tooling?
