There was a problem hiding this comment.
case c: CastBase if c.timeZoneId.nonEmpty && !c.needsTimeZone =>
c.copy(timeZoneId = None)No need to call needsTimeZone twice.

CastBase is not a case class and can't call copy

hmm, ok:
case c: CastBase if c.timeZoneId.nonEmpty && !c.needsTimeZone => c.withTimeZone(null)

…dTimeZone ### What changes were proposed in this pull request? Override the canonicalized fields with respect to the result of `needsTimeZone`. ### Why are the changes needed? The current approach breaks sematic equal of two cast expressions that don't relate with datetime type. If we don't need to use `timeZone` information casting `from` type to `to` type, then the timeZoneId should not influence the canonicalize result. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? New UT added. Closes #28288 from xuanyuanking/SPARK-31515.
