MaxGekk opened a new pull request #28767: URL: https://github.com/apache/spark/pull/28767
### What changes were proposed in this pull request? Update comments for `DateTimeUtils`.`toJavaDate` and `fromJavaDate`, and for the legacy date formatters `LegacySimpleDateFormatter` and `LegacyFastDateFormatter` regarding to the default JVM time zone. The comments say that the default JVM time zone is used intentionally for backward compatibility with Spark 2.4 and earlier versions. Closes #28709 ### Why are the changes needed? To document current behaviour of related methods in `DateTimeUtils` and the legacy date formatters. For example, correctness of `HiveResult.hiveResultString` and `toHiveString` is directly related to the same time zone used by `toJavaDate` and `LegacyFastDateFormatter`. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?
