Add current date to PDF documents

[_Dave_West_]

This doesn't seem like it should be hard, but I have been unable to find information on how to do it.

I have about 100 PDF files. Somewhere on them, I need to display "Date Printed: dd mmm yyyy", and have the current date displayed.

I don't care whether this is placed at the top of the page, the bottom, or opaque in the background.

I would like to be able to accomplish it using the batch command, but will perform manually if necessary.

I have Acrobat 7 Professional.

Can someone please help me out?

This JavaScript code adds only a expiration date to the document.

Thanks Bernd!

This code is working if I don't put any password for secure.

That means date is changed whenever I print out the file.

If I print yesterday, the date is shown yesterday's date and

if I print today, the date is shown today's date.

But after I put the password, the date shown is same date always.

I want make it works whenever I print the file, date shown on

that day's date that I print out even after I put password on the

file. (This code is not for that???)

Looks like that you don't allow changes of the document.

Well I have been using a small powerful utility for watermarking called A-PDF Watermark. This can be used even to batch add watermarks and supports show current date only when printing the PDF document and hide when viewing the document. This is fairly simple to use and you need not write any scirpts. Demo verson is available at http://www.a-pdf.com/watermark/index.htm check it out.
