tris_r,
Here's a little Worksheet Change Event that I picked up somewhere. I pick up so many I sometimes forget where. It works for me.
Cols A and B are formatted General and Col C is formatted h:mm for the difference. To place in the sheet-Right Click on the sheet tab, click view code and copy this code into the box. You can enter all the times in Col A and Col B from your keypad (800, 1000, 1130, etc and they will come out 8:00, 10:00, 11:30, etc.) I've attached a small zip file.
Hope this helps.
