Based on definition provided for ‘length of stay’, its been asked to check for timestamps as well, but Cypress is not doing it. But if we check the following record of patient "FOUR AMI", they have not qualified it in following ‘denominator exclusion’ condition ("Encounter With ICU Location Less Than 2 Days") despite that fact total days are < 2.

I have attached the Cypress screenshot for the same. 

So my query is we have to use Timestamp for calculation with date or not?
