Laravel Scheduler with multi time zone handling

I am doing ERP project in cloud base & I am using one source for multiple customers and using different database.

I want to run script every day at 00:00 with different time-zone

Here what i tried......

This is my Keel class

protected function schedule(Schedule $schedule)
{
    $schedule->command('attendance:null')->hourly();
}

This is my attendance:null command class

class AttendanceInsertNull extends Command

{ /** * The name and signature of the console command. * * @var string */ protected $signature = 'attendance:null';

/**
 * The console command description.
 *
 * @var string
 */
protected $description = 'Command description';

/**
 * Create a new command instance.
 *
 * @retu AppConsoleCommandsAttendanceInsertNull
 */
public function __construct()
{
    parent::__construct();
}

/**
 * Execute the console command.
 *
 * @retu mixed
 */
public function handle()
{
    $locations = Location::get();

    foreach ($locations as $location) {

            $schedule1 = new Schedule();
            $schedule1->call(function(){

                $timeZone = $location->timezone;

                $this->info('RUN');

            })->at('00:00')->timezone($timeZone);
    }
}

}

What i am doing is, Check with different timezone in location loop.

please anyone can help to solve this issue for me.
