stevomitric opened a new pull request, #57085: URL: https://github.com/apache/spark/pull/57085
### What changes were proposed in this pull request? Widen the input types of the `unix_seconds` / `unix_millis` / `unix_micros` functions to accept `TIMESTAMP_NTZ` and the nanosecond-precision timestamp types. For the nanosecond carrier the child evaluates to a `TimestampNanosVal`, so `nullSafeEval` reads its `epochMicros` field and `doGenCode` routes the value through a `toMicros` helper. ### Why are the changes needed? Previously these functions accepted only `TIMESTAMP_LTZ`, so callers had to cast an NTZ or nanosecond timestamp first. This brings them to parity across the timestamp families. ### Does this PR introduce _any_ user-facing change? Yes. `unix_seconds`/`unix_millis`/`unix_micros` now accept `TIMESTAMP_NTZ` and nanosecond timestamps directly. ### How was this patch tested? Added a `DateExpressionsSuite` case and end-to-end coverage in `TimestampNanosFunctionsSuiteBase`. ### Was this patch authored or co-authored using generative AI tooling?
