@panbingkun Does the Java side have similar rules? There are similar cases in the Java code, for example:

spark/sql/core/src/main/java/org/apache/spark/sql/execution/datasources/orc/OrcAtomicColumnVector.java

Lines 52 to 62 in cae2248

	if (type instanceof TimestampType) {
	isTimestamp = true;
	} else {
	isTimestamp = false;
	}
	if (type instanceof DateType) {
	isDate = true;
	} else {
	isDate = false;
	}

There are similar rules on the java side (SimplifyBooleanExpression & SimplifyBooleanReturn), which I have updated, but unfortunately, it does not recognize the above case.
