    You can't use $1, $2, ... in my(). It would be far better to avoid using $1, $2, ... altogether and use properly named variables that do not have any scoping issues.

    $string = "Fri Nov 8 15:00:02 2002:";

my ($1, $2, $3, $4, $5) = split(/ +/, $string);

    Noting that the + allows for one or more spaces.

      Oops, corrected as the use of $1, $2, etc. wouldn't work as pointed out above since they are "magic" variables used by regexps. 

      
$string = "Fri Nov 8 15:00:02 2002:";

my ($a, $b, $c, $d, $e) = split(/ +/, $string);

        I'd prefer it to match any whitespace, not just SP:

        $string = "Fri Nov 8 15:00:02 2002:";

my ($a, $b, $c, $d, $e) = split(/\s+/, $string, 5);

        Notice that I also limit the number of results to 5.

        As said in another node, you probably want to chop() off the colon, too (or use substr() instead). Also, you want to use variable names that are more descriptive than '$a, $b, $c, ...'
