   @bart-samwel  If you are referring to two test new statements i added, both are actually having timestamp in both left and right expression and returns interval. So, we have only one type, which is 
   `timestamp - timestamp returns interval`
   In the SubtractTimestamps case class we can see input date types for both left and right expressions are timestamp
   `override def inputTypes: Seq[AbstractDataType] = Seq(TimestampType, TimestampType)`
