PHP configuration: are max_execution_time and max_input_time values measured in seconds?

I'm checking my PHP configuration and I read

max_execution_time 30
max_input_time 60

Are these seconds 开发者_JAVA百科or minutes ?

If they are seconds and, let's say, I need to upload a file of 20MB with a php script (CMS).. it is usually not enough, right ?

thanks

Yes. That's right. You'd better to use FTP for uploading such big files. Your host might limit your upload size too (post_max_size).

max_execution_time does not include the time used for an upload. Please read this manual page on PHP.net
