Off hand, I would say 6:36. By the time you get your luggage, though, you can add close to an hour to your departutre (from LAX) time. One thing to consider-what time of year, and have you been here before? In the winter months, either time would get you here after dark, however, in the summer, the earlier time would get you here while it's still light, and that can make it easier to navigate your way to DLR, especially if you haven't driven it before. In June, the sun is up til after 8 p.m. Something to consider.
