class FormatDate
{
    public const FORMAT_DATE = 'd-m-Y H:i:s';

    private DateTimeFactory $dateTimeFactory;

    public function __construct(
        DateTimeFactory $dateTimeFactory
    ) {
        $this->dateTimeFactory = $dateTimeFactory;
    }

    /**
     * Get Current Format date
     *
     * @return string
     */
    public function getFormatDate(): string
    {
