Good catch, you've already find a workaround.
For code change, we don't need to make changes to calcite. If I remember
correctly, we just need to make change to the following function in
`DruidTypeSystem` to return precision for dates. Your can dive into the
`RelDataTypeSystem.DEFAULT.getDefaultPrecision` to see how calcite returns the
precision for different types.
```
@Override
public int getDefaultPrecision(final SqlTypeName typeName)
{
return RelDataTypeSystem.DEFAULT.getDefaultPrecision(typeName);
}
```
