perldoc open talks about redirecting STDOUT/STDERR to a variable - at least in perl 5.8. 

my $err;
close STDERR;
open STDERR, '>', \$err;
use Time::Piece;
$time = Time::Piece->strptime('2005-02-24 23:000', "%Y-%m-%d %H:%S");

print "[$err]\n";

You may want to open another filehandle to STDERR before closing STDERR so that you can redirect STDERR to the original console again later. Or maybe not.
