This is SQL 2000.

I have a value that's in seconds (now it could be milliseconds but since i cant see the code, i'm not sure which). I think it's millisecond...

I have below and it converts the value to 00:20:10 but i think it should be 24:20:10..that's why i think the value is actually in milliseconds..not can I fix this (convert mlillisecond to hh:mm:ss?)
declare @test as int
set @test = 87610 -- i think this is millisecond but the output should be 24:20:10 NOT 00:20:10
select convert(varchar(8),dateadd(ss,isnull((@test),0),'00:00:00'),108) Avg_Response_Time

Can you check this?

declare @test int
set @test = 87610
select case when @test/3600 < 10 then '0' + convert(varchar(10),@test/3600) else convert(varchar(10),@test/3600) end + ':' +
       case when (@test%3600)/60 < 10 then '0' + convert(varchar(10),(@test%3600)/60) else convert(varchar(10),(@test%3600)/60) end + ':' +
       case when @test%60 < 10 then '0' + convert(varchar(10),@test%60) else convert(varchar(10),@test%60) end
-- 24:20:10

in the format HH:MI:SS, the hours cannot exceed 24. At max the value would be 23:59:59 and after that the day will be increment to one resetting the HH:MI:SS to start from 00:00:00 for next day.
In your case 24:20:10 won;t be displayed instead the day would be incremented and time part would be displayed as 00:20:10

Run this and see the day got changed to 02.

declare @test as int
set @test = 87610 -- i think this is millisecond but the output should be 24:20:10 NOT 00:20:10
select convert(varchar(50),dateadd(SECOND,isnull((@test),0),'00:00:00'),120) Avg_Response_Time
-- 1900-01-02 00:20:10
