Time Expire my PDF

I have a number of PDF's that I would like to send out. However I do not want to use a password system as it takes too much time to manage.

I would like to be able to have an in-built function in the pdf that would enable me to specify when the pdf would expire.

For example 2 weeks after first opened by the user.

This does not have to be world class security just something that will stop your everday users from keeping the pdf beyond the time they are meant to.

Ideally it will be for Mac and PC. Prefer it if the user did not have to download software to unlock the PDF.

A Javascript solution could be the answer as I have read it is possible.

I must be able to alter the length of time myself and the time breaks would be something like:

1 week

2 weeks

1 month

3 months

6 months
