Filter : Machines 1 day old.

Hi, I have a filter I used on v7.0 that showed machines that are within a day of bening added to the DB.

It was this i believe.

SELECT Guid FROM vComputer
WHERE DATEDIFF(dd,CreatedDate,GetDate())<1

Now when I view the filter there are no machines even though I know it should be populated.

Is this correct formula ?
