Hi,
I have the following code that list down the starting time of each process: 
use Data::Dumper;
use Carp;
use Proc::ProcessTable;
use Time::Local::Extended qw(:ALL);

$FORMAT = "%-6s %-8s %-24s \n";
$t      = new Proc::ProcessTable;

my $now = localtime;
print "NOW: $now\n";

printf( $FORMAT, "PID", "START", "TIME_DIFF"  );
foreach $p ( @{ $t->table } ) {

    my $start = $p->start;

    #my $diff = $start - $now; #doesn't seem to work

    my $diff = 1000; # this is just a dummy

    printf( $FORMAT,
        $p->pid, scalar( localtime( $p->start ) ), $diff
        );
}

My problem is how can I find/print out the time difference (in seconds) for starting time and current time? Namely the time difference of: 
my $now = localtime;

[download]
and 
scalar( localtime( $p->start ) )

Regards,
Edward
