Update: After making some modifications (thanks to Jaap, Aristole and grinder) and one change that I made after reading through the perldoc, I know have the script much closer to what I want.

#!/usr/bin/perl -w
use strict

$name = getlogin;
@greeting = ("morning", "afternoon", "evening");
@days = qw/ Sunday Monday Tuesday Wednesday Thursday Friday Saturday /
+;
@months = qw/ January February March April May June July August Septem
+ber October November December /;
my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime;

$year += 1900;

my $greeting =
    $hour < 12 ? 0 :
    $hour < 17 ? 1 :
    2;

$min = sprintf('%02d', $min);
$current_time = $hour.":".$min;
$current_date = $months[$mon]." ".$mday.", ".$year;

if ($hour < 12) {
  print "\nGood $greeting[0], $name.\n"
}
elsif ($hour >= 17) {
  print "\nGood $greeting[2], $name.\n"
}
else {
  print "\nGood $greeting[1], $name.\n"
}
print "Today is $days[$wday], $current_date.\n";
print "The time is now $current_time.\n";
