How to calculate elapsed time on Excel at command

Hi, I have these columns in my excel spreadsheet:

A = system date
B = random date
C = elapsed days (system date - random date, where random date <= system date)

How can I recalculate column C at command? I mean, if for example there were a button for that, I would like to push it and refresh column C, always getting tha actual system date and substracting the date especified in column B; is there some simple way to implement that functionality in Excel? (using buttons was only a illustration, I only care about the functionality). I only know the very basics of using a spreadsheet, I would like a little help with this issue. I'm using Excel 2007.

Thanks in advance.

Shouldn't the formula at C just be this?

Sample In C2:   =TODAY()-B2
