Yes.

No.  If there were only one parameter, the signature would say |in any 
args|.  It actually says |in any... args| which means any number of 
arguments.  See http://www.w3.org/TR/WebIDL/#dfn-variadic-operation

Note that if you set a timeout for 1 hour from now, and then the 
computer goes to sleep for 3 hours, then the timeout will fire 1 hour 
after the computer wakes up, not immediately on wakeup.

So if you're depending on setTimeout to fire at particular wall-clock 
times, don't.  It won't.
