Set Apache Timeout

[YCMaker]

I've been trying to set the Apache timeout time; I think it defaults at 60 seconds. I have a PHP script that tells me the limit, and I've been trying everything to up it. I set the Timeout to 300 in httpd.conf under /etc/httpd/conf... is there somewhere else it needs to be edited?
Thanks for your help!

It could be max_execution_time or max_input_time in /usr/local/lib/php.ini.
