Hello, I need to write a script that kicks off several processes at once. But between each fork, there should be delay of n seconds. I am using Parallel:ForkManager and know that I have to use sleep but not sure on the how. 
#!/usr/software/bin/perl5.8.8 -w

use strict;
use warnings;
use Cwd qw(abs_path);
use Parallel::ForkManager;

my $pm = new Parallel::ForkManager(8);
$pm->run_on_finish(sub {
    my($pid, $exit_code) = @_; 
    my $output  = "$pid has finished with exit code $exit_code.\n";
    print $output;
});
foreach my $x (0..2) {
    $pm->start($x) and next;
    sleep(1); # I want to sleep for 2 mins before the next process kic
+ks off.
    my $time = time;
    print "$x\n";
    print "$time\n";
    $pm->finish();
}
$pm->wait_all_children;

The above code is wrong because every process sleeps for 2 mins and they resume at the same time. Instead I would like process 0 to start, 2 mins goes by, then process 1 joins, 2 mins go by and then process 3 joins, etc... Is there someway to do this? Thanks for your help.
