I have a script that views one element from a hash at a time using a url_param. Ie.

http://www.mysite.com/cgi-bin/employees.pl?id=Mon%20Jan%2026%2006:08:4
+8%202004

I'm using localtime so I can sort my hash in reverse timely order (though I can probably use an increment on the key as a $num++ and reverse that, but that's a different topic)..

If I am viewing id=Mon%20Jan%2026%2006:08:48%202004, is it possible to make a BACK button that when the user clicks it, it will show them the first previous dated hash? I want to be able to travel through all the database using back and forward buttons, any idea how this can be done?

An example of my hash looks like:

%people( "$time" => "$name|$email|$address");

And when you the url points at id=$time, I do a split on | and break it back into separate variables.
