I'm using Computed Columns to provide me with the following information:

Hours, Minutes, and Seconds between a Start DateTime and Finish DateTime (Where Minutes and Seconds are between 0 and 59 and Hours can be any value 0 or greater)

Computed Column for Seconds:

datediff(second,[Start],[Finish]) % 60

Computed Column for Minutes:

floor(datediff(second,[Start],[Finish]) / 60.0) % 60

Computed Column for Hours:

floor(datediff(second,[Start],[Finish]) / 3600.0)

Here's the table for reference

Note: I'm also calculating TotalElapsedSeconds, TotalElapsedMinutes, and TotalElapsedHours in other computed columns, but those are easy. I just feel like I might be missing out on a nice built in function in SQL.
