MaxGekk opened a new pull request #23358: [SPARK-26424][SQL] Use java.time API in date/timestamp expressions
URL: https://github.com/apache/spark/pull/23358
 
 
   ## What changes were proposed in this pull request?
   
   In the PR, I propose to switch the `DateFormatClass`, `ToUnixTimestamp`, `FromUnixTime`, `UnixTime` on java.time API for parsing/formatting dates and timestamps. The API has been already implemented by the `Timestamp`/`DateFormatter` classes. One of benefit is those classes support parsing timestamps with microsecond precision. Old behaviour can be switched on via SQL config: `spark.sql.legacy.timeParser.enabled` (`false` by default).
   
   ## How was this patch tested?
   
   It was tested by existing test suites - `DateFunctionsSuite`, `DateExpressionsSuite`, `JsonSuite`, `CsvSuite`, `SQLQueryTestSuite` as well as PySpark tests.
