max_execution_time starts when the entire request has been received (or, more accurately, once PHP script execution has begun). Upload times don't trigger it to start. If I recall correctly, max_input_time includes time taken to copy the file to the tmp directory and to parse the file for metadata, but not the upload time either (it does start prior to max_execution_time though). This value is set to -1 by default meaning it uses the value from max_execution_time instead. You're more likely to run into Apache, Nginx, or PHP FPM timeouts. I can't remember exactly which timeout, but I remember there is one in Apache or FPM that is affected by upload time.
