Why can't classical information be transmitted through quantum entanglement by measuring time between change events?

If the effect of measurement in quantum entanglement occurs instantaneously why can't it be used to transmit classical information faster than light?

I'm based my question off this seemingly well cited Wikipedia article: http://en.wikipedia.org/wiki/Quantum_entanglement#cite_note-10

Edit: It would seem that my question should be more focused on why we can't use change as a method of data transmission.
