Как добавить дату и время сборки в приложение на CRA2?

getBuildDate.ts

import preval from 'preval.macro';

const buildDate = new Date(Number(preval`module.exports = new Date().getTime();`));

/**
 * Дата сборки.
 * @link https://stackoverflow.com/questions/53028778/how-to-show-build-datetime-on-my-react-web-app-using-create-react-app
 * @link https://gist.github.com/khusamov/2a9ce98bd1e5eff247502bdadaa4443a
 */
export default function getBuildDate(): Date {
	return buildDate;
}

getBuildDateString.ts

import preval from 'preval.macro';
import moment from 'moment';

const buildTimestamp = Number(preval`module.exports = new Date().getTime();`);
const lastUpdateMoment = moment.unix(buildTimestamp / 1000);

/**
 * Дата сборки в виде строки.
 * @link https://stackoverflow.com/questions/53028778/how-to-show-build-datetime-on-my-react-web-app-using-create-react-app
 * @link https://gist.github.com/khusamov/2a9ce98bd1e5eff247502bdadaa4443a
 */
export default function getBuildDateString(): string {
	return lastUpdateMoment.format('DD.MM.YYYY HH:mm:ss');
}

/**
 * Дата сборки.
 */
export function getBuildDate(): Date {
	return lastUpdateMoment.toDate();
}

/**
 * Год сборки.
 */
export function getBuildYear(): number {
	return lastUpdateMoment.year();
}
