That is a server error, not a vbulletin error - more specifically a php error. You need to increase the max_execution_time variable in php.ini. If you don't have access to change the variables, you will have to ask your host. However, even though it is a php error, and not a vbulletin error, that doesn't mean that you didn't do something wrong in vbulletin to cause this limit to be reached. So, you may want to reconsider whether you want to make that code change.
