Question : time formats - coming up with totals

Hi, I have a table with time formats like this:

TL_TimeIn      TL_TimeOut
4:50:38 PM      5:55:02 PM
2:51:37 PM      5:58:53 PM
2:55:20 PM      6:00:42 PM
2:18:32 PM      2:59:19 PM

and I need to come up with a total number of hours - what's the best way to do this?
thanks!

Answer : time formats - coming up with totals

SELECT clng(Sum(TL_TimeIn - TL_TimeOut)* 24) as MyTotalHours
FROM myTable;

Do you want the minutes too???
