Review comment:
There are several places that we need to decide if the data types are among
`DATE`, `TIME` and `TIMESTAMP`, can we make some effort to abstract a method in
EnumUtils.java like:
```java
representsAsInterType (type) {
return (type == date || type == time || type == timestamp)
}
```
to decide if we need to handle specifically when we need to do that ?
