Maxim Gekk created SPARK-27401:
----------------------------------
Summary: Refactoring conversion of Date/Timestamp to/from java.sql.Date/Timestamp
Key: SPARK-27401
URL: https://issues.apache.org/jira/browse/SPARK-27401
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Maxim Gekk
The fromJavaTimestamp/toJavaTimestamp and toJavaDate/fromJavaDate can be implemented using existing methods DateTimeUtils like instantToMicros/microsToInstant and daysToLocalDate/localDateToDays. This should allow:
# To avoid invocation of millisToDays and time zone offset calculation
# To simplify implementation of toJavaTimestamp, and properly handle negative inputs
# Detect arithmetic overflow of Long
