perl creating a new folder named with todays date

I have a perl script that opens a webpage, gets all the .txt links from the page and savesw each link as a file in $SaveDir

Right now $SaveDir is static  

my $SaveDir = "I:/SECDocs/20070730/";

Every time it runs, I manually have to create a new folder with a matching name.

I would like script to create a new folder everyday on its own like:
my $SaveDir = "I:/SECDocs/$TodaysDate/";


How do I set $TodaysDate to be todays date and create a folder with that name?



Heres what I have:


#!/usr/bin/perl
use strict;
use warnings;
use LWP::Simple;
use Data::Dumper;
use HTML::SimpleLinkExtor;

#Update these as necessary

my @Pages = (
