declare @date1 AS DATETIME
declare @date2 AS DATETIME
DECLARE @diff AS INT

SET @date1 = CONVERT(datetime, '10/3/2012 12:02:16 PM')
SET @date2 = CONVERT(datetime, '9/21/2012 12:01:32 AM')

SET @diff = DATEDIFF(SS, @date1, @date2)
SET @diff = CASE WHEN @diff < 0 THEN @diff * -1 ELSE @diff END
SELECT
(CASE WHEN LEN((@diff/3600))>1 THEN CONVERT(VARCHAR, (@diff/3600)) ELSE '0' + CONVERT(VARCHAR, (@diff/3600)) END) + ':' +
(CASE WHEN LEN(((@diff%3600)/60))>1 THEN CONVERT(VARCHAR, ((@diff%3600)/60)) ELSE '0' + CONVERT(VARCHAR, ((@diff%3600)/60)) END ) + ':' +
(CASE WHEN LEN(((@diff%3600)%60))>1 THEN CONVERT(VARCHAR, ((@diff%3600)%60)) ELSE '0' + CONVERT(VARCHAR, ((@diff%3600)%60)) END )

declare @Date2 datetime = '9/21/2012 11:01:32 PM'

SELECT STUFF( CONVERT(varchar(8),timediff,108),1,CHARINDEX(':',CONVERT(varchar(8),timediff,108))-1,DATEDIFF(dd,0,timediff) * 24 + DATEPART(hh,timediff))

FROM
(
SELECT DATEADD(ss,ABS(DATEDIFF(ss,@Date1,@Date2)),0) AS timediff
)t
