If the question is how far in advance do you need to arrive, the answer is even 45 minutes is enough time.
However, if the question is how much extra time do I need to leave for the drive to allow for traffic, then answer is whatever waze says plus an extra hour!
(I know OP is asking about 6am on a Sunday so 99.9% chance is that there will be no traffic. I am talking about in general.)
