Modifying Date/Time stamped value to calculate Days Since

Hi,
My data set contains 'Order Date' (Day/Month/Year format) in col 'A' and 'Shipped to Store Date' (which is a date/time stamp combination) col 'B'. I would like to calculate the 'Days Since Order' col 'C' but cannot seems to figure out how to break and re-format the Ship to Date value.

Also, unsure if this is best done through vba or formula.

Any guidance would be appreciated.

Hi Ernest,
These are not real excel dates and I tried the formula above and it returned FALSE. Any other suggestions on how I can convert these values into dates?
