If you want to identify machines that have been newly discovered within the last 24 hours, then you have use the query below.

select  
      SMS_R_System.Name,   
      SMS_R_System.CreationDate   
 from SMS_R_System  
      where DateDiff(dd,SMS_R_System.CreationDate, GetDate ()) <= 1

If you want to change the 24 hours value, then just amend the where value of 1 (this is a day value not hour value) to whatever you want it to be.
