Playing With Time

If we have mistaken $67,02$ beats to a second as $60$ beats to a second, light speed $c$ as measured would have gone further by a factor of $\cfrac{67.02}{60}$ so

$280.735414*\cfrac{67.02}{60}=313.581457438$

because we have a longer second ($\cfrac{1}{60}$ as oppose to $\cfrac{1}{67.02}$).

What happens at or about $67.02\,Hz$?  The length of a second is in doubt.
