3 different ways:

#!/usr/bin/perl -wT

use Time::HiRes;
use Time::HiRes qw( time );

my $start_time = [Time::HiRes::gettimeofday()];
my $start = Time::HiRes::gettimeofday();
my $start_a = time();

print "hey\n";

my $diff = Time::HiRes::tv_interval($start_time);
my $end = Time::HiRes::gettimeofday();
my $end_a = time();

print "diff 1 = $diff\n";
printf("diff 2 = %.6f\n", $end - $start);
printf("diff 3 = %.6f\n", $end_a - $start_a);

end code
