Hiding Iframe based on other page age

[lajme]

I have a main page on a web site that includes an Iframe with current news headlines. Issue is that the Iframe source page is often stale (Old News).
I want to be able to determine the age of the Iframe source page and if the last modified date is over 30 days old, then I want to hide the Iframe.

Any help would be appreciated.
