------------------------------------
Summary: It's weird that copy julianDateFloor from DateTimeUtils
and change the implementation
Key: FLINK-14810
URL: https://issues.apache.org/jira/browse/FLINK-14810
Project: Flink
Issue Type: Improvement
Components: Table SQL / Planner
Reporter: Zhenghua Gao
In SqlDateTimeUtils we copied *julianToLocalDate* from DateTimeUtils and
changed the implementation. It's weird to use an *entirely* *different*
implementation to do the same thing.
One possible improvement of the new one is support TimeUnitRange.QUARTER. But
the logic to calculate year/month/day is totally different.
