phpinfo system and build date

The phpinfo function lists the system ... But is it the system that PHP
was compiled on OR the system that PHP is executing on? I took a sneak
peek at the source code and I am leaning toward the latter... Same
question for the build date. Is it the build date for PHP or the build
date for the system?

Thanks.

It's the system PHP is currently running on.
