и время\r\n- затем мы используем метод `getTime()` для получения количества миллисекунд, прошедших с 1 января 1970 года (`Epoch time`) до текущей даты и времени\r\n- это значение мы передаем в конструктор класса `Timestamp`, чтобы создать объект с текущей датой и временем.\r\n\r\nЭтот код в консоль текущий `timestamp` , например:\r\n\r\n```\r\nТекущий timestamp: 2023-04-13 15:25:30.123456789\r\n```\r\nТочное значение `timestamp` будет отличаться в зависимости от текущей даты и времени.\r\n\r\n***\r\n\r\nОбратите внимание, что класс `java.sql.Timestamp` наследует от класса `java.util.Date`, поэтому его также можно использовать везде, где используется класс
