Is there a better way to get the hour information, or is this the most optimized mode, please need help



 CASE 
     WHEN DATEPART(Hour, StartDTM) = 1 THEN
          CASE
          WHEN DATEPART(Hour, EndDTM) = 1 THEN
          CAST(DATEPART(minute, EndDTM) - DATEPART(minute, StartDTM) AS FLOAT)/60
          ELSE
          CAST(60 - DATEPART(minute, StartDTM) AS FLOAT)/60
    END
    WHEN DATEPART(Hour, EndDTM) = 1 THEN    
        CAST(DATEPART(minute, EndDTM) AS FLOAT)/60
         WHEN 1 BETWEEN DATEPART(Hour, StartDTM) AND DATEPART(Hour, EndDTM) THEN 1   
         ELSE 0
    END AS '1AM',


Thank you very much for the helpful info.
