Passing variable into perl system commands

Hi guys, I'm having issues getting the following snippet of my script to work and was hoping for some suggestions.
I'm trying to pass a variable in perl system with wget.

This is what I need help with:

Code:
#!/usr/bin/perl
use strict;
use warnings;
use POSIX qw(strftime) ;

my $TimeStamp=strftime "%Y%m%d",localtime ;
system('wget -q --no-check-certificate -O /tmp/DataFile_$TimeStamp "https://foobar.com/html"') ;

I can't get the $TimeStamp to interpolate into the system command.

Any ideas on solving this?

Thanks in advance.

This module provides routines to format dates. They correspond to the libc routines. &strftime() supports a pretty good set of coversions -- more than most C libraries. strftime supports a pretty good set of conversions. The POSIX module has very similar functionality. You should consider using it instead if you do not have allergic reactions to system libraries. GENESIS
