Simple PHP Question

This is the example I am using:

Code:

$d=date("D");

Where does php get the date from? I changed my Windows clock to Friday but no difference was seen. Is it the BIOS clock or some ntp server?

 

Is this on a server or your machine? It pulls from whatever it's stored on from what I can tell.

This is what I use on O2k:

PHP:

 <? echo date ("F jS, Y"); ?> 

 

It is on a server... so it would be on the server's time?

Thanks. I wasn't sure if it was like how javascript get it from the computer.
