What do you mean 'expires'?
 
by "expire" i mean permanently close so that one is unable to open it. i thought there was a way to govern this and i was wondering how to check if one such government was in place.
 
maybe there is, never heard of or come across a pdf I couldn't open many of them years old,
maybe they didnt have this timelock you speak of ?
interested to see what responses others offer

By 'expire', do you mean making the .pdf document read only, so that one can view the contents but not make any modifications? Or are you thinking that you can install a 'time bomb' in the document, so that after the trigger date, the file erases itself or otherwise renders itself unreadable by anyone?

If the latter, you might read this Acrobat User's forum thread:

You can also google 'Acrobat file self destruct' for other methods and discussions.
