OK, as the site only allows certain types of file to be uploaded, the file attached is called hoursdifference.xls.txt - get rid of the .txt on the end and you should be able to open it in Excel.
Hopefully the spreadsheet should be self-explanatory.
I've put formatting in there to make it look like 2 hrs and 30 minutes (for example) instead of 2.5 hrs. If you don't want it to look like that, simply change the formatting from "custom: # ?/60" to numbers.
As always, any questions just post back and I'll be happy to explain.
