It sounds like you're trying to do things on the client side (in the form) that should be done on the server side (the Perl generating the form and receiving its data). You should not let the user send a timestamp, s/he can edit it. And you should probably only use that kind of unique value from the form to make sure the form was from the page/tab/submission that was expected and not a duplicate.

Perhaps if you told us the problem you're trying to solve instead of the technique, we might have better ideas for you.
