    不用第三方提供的时间
    不会因为用户电脑 /时区设置异常而出错

    可以在服务器部署时间源程序
    可以用 Javascript
  • UTC
  • 时区
  • Javascript
  • 时钟

    页面生成时，或者页面加载好之后用 XHR 获得初始的 Unix Timestamp ，然后每 1000 毫秒将这个值 +1 ，然后用 moment.js 格式化显示。

    @ryd994 到分钟级别就行


    @Livid 正在尝试
    btw: 手机端看有 YouTube 链接的帖子时， YouTube 框体会跑出界面而且 UI 会很奇怪。具体的你拿 iPhone 手机打开一下你那个三国志的帖子

    页面载入时通过 XHR 请求任意动态资源的 HEAD 获得服务器当前时间，并和本地时间对比算出差值

    接着每隔一秒用本地时间加上差值展示出来
