Philip Johnson writes: I am referring to the time it took for the universe to be 50 billion light years in size. Evolution teaches that as a result of Inflation this occurred in less that a trillionth of a second, whereas creationists say it took several days.

As for cosmology, as far as I know the inflation model is an hypothesis. It is not settled science.
