If you need this information to profile and optimize your program, use Devel::NYTProf.

If you need this information to display statistics while your program runs (or something similar), use Time::HiRes:

use Time::HiRes qw( gettimeofday tv_interval );

my $t0      = [gettimeofday()];
...
my $elapsed = tv_interval( $tv );
