As long as the time() calls aren't invoked in the default no-timeout
case, I doubt that the small additional slowdown matters too much.
Still, one could ask why we are expending extra cycles to make the
timeout more accurate. Who the heck needs an accurate timeout on
connect? Can you really give a use-case where the user won't have
picked a number out of the air anyway?
