I recall you asking about this back in March.

You are correct that the modification date of a folder doesn't change
unless files are added, removed, or renamed in the folder. So you'll
have to look at the modification date of the individual files within the
folder. Here's how to get the modification date of a specified file,
"source":

tell application "Finder" 
        set modDate to the modification date of (file source) 
        log modDate 
end tell 

As I mentioned back in March, there are applications that synchronize
folders in classic Mac OS, like Folder Synchronizer (see the "Previous
Versions" link on this page):
