[jira] [Created] (SPARK-28955) Support for LocalDateTime semantics

Bill Schneider created SPARK-28955:
--------------------------------------

             Summary: Support for LocalDateTime semantics
                 Key: SPARK-28955
                 URL: https://issues.apache.org/jira/browse/SPARK-28955
             Project: Spark
          Issue Type: Wish
          Components: SQL
    Affects Versions: 2.3.0
            Reporter: Bill Schneider


It would be great if Spark supported local times in DataFrames, rather than only instants. 

The specific use case I have in mind is something like
 * parse "2019-01-01 17:00" (no timezone) from CSV -> LocalDateTime in dataframe
 * save to Parquet: LocalDateTime is stored with same integer value as 2019-01-01 17:00 UTC, but with isAdjustedToUTC=false.  (Currently Spark saves either INT96 or TIME_MILLIS/TIME_MICROS which has isAdjustedToUTC=true)
