A "light year" is not an amount of time. 

It's an amount of distance ... the distance that light travels
through space in one year.

1 light year  =  5,878,625,372,000 miles
                     (rounded to the nearest thousand miles)

1 light-year  =  9,460,730,473,000 kilometers 
                     (rounded to the nearest thousand kilometers)
