MaxGekk opened a new pull request #28408: URL: https://github.com/apache/spark/pull/28408
### What changes were proposed in this pull request? In the PR, I propose to fix two legacy timestamp formatter `LegacySimpleTimestampFormatter` and `LegacyFastTimestampFormatter` to perform micros rebasing in parsing/formatting from/to strings. ### Why are the changes needed? Legacy timestamps formatters operate on the hybrid calendar (Julian + Gregorian), so, the input micros should be rebased to have the same date-time fields as in Proleptic Gregorian calendar used by Spark SQL, see SPARK-26651. ### Does this PR introduce any user-facing change? Yes ### How was this patch tested? Added tests to `TimestampFormatterSuite` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
