title: catch max_input_time php error
body: <p>I need to prove to my sys admin that <strong>max_input_time</strong> in php.ini is what's stopping me from uploading large files to the server, but he wont increase it until I show him a proper error.</p>
  
  <p>I looked at the manual but couldn't find anything about it.</p>
  
  <p>Does anyone know of a method for proving this?</p>
  
  <p>Thank you</p>
