Actually, I may have been a little poor with my calculations. If we take only significant digits, we get a time dilation of nil (gamma works out to 1.0). Here I'm assuming what I was taught is actually true, that being that you can only be as certain as your least certain measurement plus one decimal place. Therefore, .1c and 80 years being our "data", we can only be significant to the tenths place. That gives us the value of gamma being equal to 1.0 and the time dilation being nil.

Either way, not much of an effect.
