Into the city around midnight, not more than 30 minutes. For a return trip in the afternoon - well depending upon departure time and the area of the city you are leaving from, you might want to allow significantly more travel time. If you are near to an expressway entrance it can be as little as 30/40 minutes, if not it could easily be double that. Traffic in general starts to slow down noticeably after about 3pm as the evening peak gets underway.
