The simplest approach is to not use a lexical variable but a global variable:

use vars '$start';
sub Start_timer : Test(startup) {
    $start = time;
    ...
};

sub End_timer : Test(shutdown) {
    print time - $start;
    ...
}

If you really want to avoid global variables for things like that, you could use the state keyword and a function to read the start time:

sub get_or_init_start_time {
    state $start ||= time;
}

You need to call this function in two places, once to initialize the $time variable and once to retrieve the value.
