Print date last file in folder was updated

Hi.

I have moved a website from one server to another and updated it to run in PERL as the new host didn't have ASP enabled by default and I couldn't be bothered to get my domain moved to one that does. Anyway, I used to have a page which checks the folder which contained all the pages in this particular site and displayed the most recently modified date of the files.

The code is:

<%@ Language=VBScript %>

<%
	dim fs,fo,x
	dim MostRecentDate
	set fs=Server.CreateObject("Scripting.FileSystemObject")
	set fo=fs.GetFolder("D:\webroot\website\")

	for each x in fo.files
		if x.DateLastModified > MostRecentDate then
			MostRecentDate = x.DateLastModified
		end if
	next

	set fo=nothing
	set fs=nothing

Response.Write "<p class='footer'>Last Updated by Me on: " & MostRecentDate & "</p>"
%>

Code (markup):

Now, can something similar be done so that my site running in PERL will do the same thing? I have seen code that can check a specific file but haven't been able to work out how to check a folder.

Any help much apreciated!
