Here's a module I made that gets a lot of use. It times the total runtime of a perl script and prints the runtime and script name at the terminal. The only thing needed to make it time a script is to put "use Timer::Runtime" into the script.

I'd like to request some peer review and ask for any suggestions.

The output if this is used on 'myscript.pl' would look like: 
myscript.pl Started: Thu Aug 12 20:34:49 2010
myscript.pl Finished: Thu Aug 12 20:34:49 2010, time = 00:00:00.000114

Here is what the module looks like: 
package Timer::Runtime;
use strict;

use Time::Elapse;

Time::Elapse->lapse( my $now);

BEGIN {
    print "$0 Started: " . ( scalar localtime ) . "\n";
}

END {
    print "$0 Finished: " . ( scalar localtime ) . ", time = $now\n";
}
