> At present Quickstep has two types for representing date - 
> 1. Date (Year, month and date)
> 2. Datetime (Year, month, date, hours, minutes, seconds) etc.
> For TPC-H tables, the first type is sufficient.
> Despite the presence of two date types, the representation uses the second type by default, which is excessive for operations used in TPC-H. We should use only type 1 when the parser finds DATE token and use type 2 for DATETIME token.
