MaxGekk opened a new pull request #29892: URL: https://github.com/apache/spark/pull/29892
### What changes were proposed in this pull request? Explicitly document that `current_date` and `current_timestamp` are executed at the start of query evaluation. And all calls of `current_date`/`current_timestamp` within the same query return the same value ### Why are the changes needed? Users could expect that `current_date` and `current_timestamp` return the current date/timestamp at the moment of query execution but in fact the functions are folded by the optimizer at the start of query evaluation: https://github.com/apache/spark/blob/0df8dd60733066076967f0525210bbdb5e12415a/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/finishAnalysis.scala#L71-L91 ### Does this PR introduce _any_ user-facing change?
