js时间样式

function getCurrentTime() {
    const now = new Date();
    const year = now.getFullYear();
    const month = String(now.getMonth() + 1).padStart(2, '0');
    const day = String(now.getDate()).padStart(2, '0');
    const hours = String(now.getHours()).padStart(2, '0');
    const minutes = String(now.getMinutes()).padStart(2, '0');
    const seconds = String(now.getSeconds()).padStart(2, '0');

    return `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
}

console.log(getCurrentTime()); // 输出类似：2023-10-05 14:30:15

const options = { year: 'numeric', month: 'long', day: 'numeric', hour: '2-digit', minute: '2-digit', second: '2-digit' };
const formatter = new Intl.DateTimeFormat('zh-CN', options);
console.log(formatter.format(new Date())); // 输出类似：2023年10月5日 下午2:30:15

const utcDate = new Date(Date.UTC(2023, 9, 5, 14, 30, 15));
console.log(utcDate); // 输出 UTC 时间

const moment = require('moment');
console.log(moment().format('YYYY-MM-DD HH:mm:ss')); // 使用 moment.js 格式化时间
