不使用模块的Node.js日期格式转换

const currentDate = new Date();

const year = currentDate.getFullYear();
const month = String(currentDate.getMonth() + 1).padStart(2, '0');
const day = String(currentDate.getDate()).padStart(2, '0');
const hours = String(currentDate.getHours()).padStart(2, '0');
const minutes = String(currentDate.getMinutes()).padStart(2, '0');
const seconds = String(currentDate.getSeconds()).padStart(2, '0');

const formattedDate = `${year}-${month}-${day}`;
const formattedTime = `${hours}:${minutes}:${seconds}`;

const formattedDateTime = `${formattedDate} ${formattedTime}`;
