获取网络服务器的当前时间 [英] Get current time of webserver

问题描述

我想知道是否可以获取网络服务器的当前时间.例如，我想访问某个任意网站，并获取托管该网站的网络服务器的当前时间.

I was wondering if it were possible to get the current time of a webserver. So for example, I'd like to go on some arbitrary website, and get the current time of the webserver hosting the website.

如果它有所作为，我知道一些 php、html 和 css.我知道 C++，但我怀疑这会有所帮助.

If it makes a difference, I know some php, html and css. And I know C++, though I doubt that'd help.

谢谢.

<?php
print_r(get_headers("http://www.google.com"));
