Here I want to access get the values returned values from the subs, by using threads I have wrote the code as below: 
use threads;
use Data::Dumper;

my $hash1;
my $hash2;

while(1) {
    async( \&sub1)->detach;
    async( \&sub2)->detach;

    print '$hash1'. Dumper($hash1) ."\n";
    print '$hash2'. Dumper($hash2) ."\n";
    print "_______________________________\n";
    sleep(10);
}

sub sub1
{
        my $now = `date "+%Y-%m-%d %H:%M:%S"`;
        chomp($now);
        $hash1->{'time'} = $now;
}


sub sub2
{
        my $now = `date "+%Y-%m-%d %H:%M:%S"`;
        chomp($now);
        $hash2->{'time'} = $now;
}

But when I execute this program getting the values like:
$hash1$VAR1 = undef;
$hash2$VAR1 = undef;
_______________________________
Here I want to get the values of both hash in Main program;
