Excel/Formula that calulates hours and minutes worked


I am trying to write a formula that calculate time worked NOT in military time. My issue is that I don't get proper calculations when the hours worked go over a 24 hour period.
Example: Time In: 12/12/12 7:15 AM Time Out:12/13/12 11:30 AM. I subtract the time in from time out and format the answer in time I lose 24 hours in my answer, but the minutes are correct. If my formula is subtract time in from time out *24 then my hours are correct, but the minutes are in fraction format instead of actual minutes.  I am sure I am missing a simple step, but I cannot figure it out!  Can you help?

On a blank sheet, enter into cells A1:A2

12/12/2012  7:15:00 AM
12/13/2012  11:30:00 AM

Right-click on cell C1 and choose Format Cells, Number, Category: Time, Type: 37:30:55, OK.

Enter into cell C1


C1 will display 28:15:00, meaning that between the time in A1 till the time in A2 the elapsed time is 28 hours, 15 minutes, zero seconds.

I can answer questions relating to MS Excel formulas, or to programming with vba (Visual Basic for Applications) in the Excel environment. Please follow the following guidelines: your question should focus on one specific issue you want to learn. It's beyond the scope of this free service for me to create entire projects or complex vba solutions for you from scratch. You should be able to do most of the work yourself, and come here when you need help with a specific point you're stuck on. ALWAYS include a simple, concrete example illustrating what you want to learn. Explain this example in detail in the text of your question (what data is in which cells of which sheets, etc). Be very precise about the results you want, using this sample to make the logic clear. Always keep these examples SIMPLE. Never e.g. use 18 worksheets in your example if using 2 or 3 will do. Never use ranges like AI567:BB865 if using a range like A1:B3 will do. Thanks.
