    How about something like this to avoid the self-join? Uses Sean's setup data.

    SELECT Div_time, Unit_id

    ,TimeDifferenceMin=DATEDIFF(minute, MIN(Filled_Time), MAX(Filled_Time))

    FROM #Something

    GROUP BY Unit_id, Div_time

    HAVING MAX(Filled_Time) <> MIN(Filled_Time)

    Edit: Added the time difference.

    +1 Thanks Dwain, not sure why I didn't come up with it.
