Excel 2007

I have a need to insert the file creation date into a workbook. I could
swear that I've done this before, in earlier versions of Excel.
However, I'm not real familiar with Excel 2007 yet and I'm having a hard
time figure out how to do this. I went to the Formulas ribbon and then
to Insert Function and looked through the date and time functions, but
did not see what I need.

Is there a way to insert the file creation date into an Excel workbook?
