I am writing a script to test a handful of mail accounts on our mailserver. This script needs to run automatically every half hour on a Windows machine, unfortunately, I don't have access to cron. My questions are: Is the script below the way to do this? and; Can anyone recommend a better method? 
#!/usr/bin/perl -w

use strict;

use MIME::Lite;
use Date::Calc qw(Today_and_Now
                  Date_to_Text_Long);

my $gmt;
my $sleeptimer;
my ($year,$month,$day, $hour,$min,$sec) = Today_and_Now([$gmt]);
my $sig = "\n\nHere is my sig";

my $time = sprintf("%s, %s:%s:%s",
            Date_to_Text_Long($year,$month,$day),
            $hour,
            $min,
            $sec
            );

my $msg = MIME::Lite->new(
                 From     =>'test@account.com',
                 To       =>'test1@account.com',
                 Cc       =>'test2@account.com, test3@account.com',
                 Bcc      =>'test@account.com',
                 Subject  =>'This is a test message',
                 Data     =>"This message was sent from my script:\n\n
+$time$sig"
                 );
                 
if ($min > 30) {
    $sleeptimer = 60 - $min;
    $sleeptimer = $sleeptimer * 60;
} elsif ($min < 30) {
    $sleeptimer = 30 - $min;
    $sleeptimer = $sleeptimer * 60;
} else {
    $sleeptimer = 1800;
}

if ($sleeptimer ne 1800) {
    sleep $sleeptimer;
    }

do {$msg-> send('smtp', "mail.server.com", Timeout=>60);
    sleep 1800;
    redo;
    }
