What does microtime do?

Hello what is microtime supposed to do when you add it to a php function. As an example only:

 

mt_srand((double)microtime()*100000);

 

Please let me know, thank you very much.

thst for Random numbers

microtime() returns the current Unix timestamp with microseconds. This function is only available on operating systems that support the gettimeofday() system call.
