Can a PDF automatically update information?

Hi, I'm a graphic designer working with a compnay to try and improve their product labling and i need some help.

The company manufactures made-to-order products which have to have a manufacturing date and an expiry date.  to save time and cost they print the dates as part of the lable with each product lable being printed individually and as needed as they have over 10,000 standard product combinations curently available.

At the moment they're lables are designed in microsoft Word, which can automatically insert todays date and todays date +12 for the expiry.

questions is, can PDFs do this too?

What I'd like, is to rebuild all the lables in real design software (not word) and thensave it as a PDF, this would stop the lables from being altered by accident when they are opened up to print but I need some way of printing the dates on them.

If they can handle this sort of live information, what software do i need to create it?

Regards Jackal.
