In C, how to get the date from a website?

I know there’s a command from a C program in Linux that will allow you to retrieve the date from a site, say Google.

But from C/C++, how do you get the date from a website, in the Windows environment?

What do you mean with date?
The date when the file has been last modified
or what time it is on the machine where the website is?
