SQL Server 2008 genera una serie de fechas y horas

Usar un CTE recursivo

declare @StartTime datetime = '2011-07-20 11:00:33',
    @EndTime datetime = '2011-07-20 15:37:34',
    @Interval int = 554 -- this can be changed.

;WITH cSequence AS
(
    SELECT
       @StartTime AS StartRange, 
       DATEADD(SECOND, @Interval, @StartTime) AS EndRange
    UNION ALL
    SELECT
      EndRange, 
      DATEADD(SECOND, @Interval, EndRange)
    FROM cSequence 
    WHERE DATEADD(SECOND, @Interval, EndRange) < @EndTime
)
 /* insert into tmp_IRange */
SELECT * FROM cSequence OPTION (MAXRECURSION 0);
