Military time in excel

[priceassist]

I am working on a spreadsheet and my column E is my start time and column F is my stop time and i need to calculate the minutes in column G. =F-E=G doesn't always work. The time is military time and I want to be able to formulate it without needing to put the colons in. I want to be able to program the spreadsheet so when i plug in the start and atop time column G automatically calculates.
