(
inTime varchar(8)
)

SET NOCOUNT ON
INSERT INTO #Table1 VALUES('02:00:48')
INSERT INTO #Table1 VALUES('22:00:22')
SET NOCOUNT OFF


SELECT
    CONVERT(varchar(2),TotalSeconds/3600)
        +':'
        +RIGHT('00'+CONVERT(varchar(2),(TotalSeconds-(TotalSeconds/3600*3600))/60),2)
        +':'
        +RIGHT('00'+CONVERT(varchar(2),TotalSeconds-((TotalSeconds/3600*3600)+(((TotalSeconds-(TotalSeconds/3600*3600))/60)*60))),2) AS Answer
        ,DATEADD(second,dt.TotalSeconds,CONVERT(datetime,'1/1/1900')) AS AnswerIncrementingDays

    FROM (SELECT
              SUM(DATEDIFF(second,CONVERT(datetime,'1/1/1900'),CONVERT(datetime,'1/1/1900 '+inTime))) AS TotalSeconds
              FROM #Table1
         ) dt

select right('0' + cast(TotalHours + TotalMinutes / 60 as varchar), 2) + ':' + right('0' + cast(TotalMinutes % 60 as varchar), 2) + ':' + right('0' + cast(Seconds as varchar), 2)
from (
    select TotalHours, TotalMinutes + TotalSeconds / 60 as TotalMinutes, TotalSeconds % 60 as Seconds
    from (
        select 
            TotalHours = SUM(cast(substring(a, 1, 2) as int)),
            TotalMinutes = SUM(cast(substring(a, 4, 2) as int)),
            TotalSeconds = SUM(cast(substring(a, 7, 2) as int))
        from (
            select '02:00:48' a
            union
            select '22:00:22'
        ) a
