It is a scientific fact that Spaniards have internal clocks that run on some whacked out Iberian quartz crystals that can not be found in North America . This is not necessarily a bad thing but it is a force to be reckoned with if you are one of those time - constricted / restricted anal butt - clenching clock - watchers who like meetings and people to be punctual and for things to happen in a timely manner . Like me . The reality is that quite simply , things tend to happen late here .

Question: What issues does the quartz clock cause ?
Answer: None of the above choices .It can cause people to be late to important places .It can confuse people with the time .The time jumps around too much on the clock .
