What times does Adele go on stage and start performing (21 concert tour)?

I'm going to her show this weekend at the Greek but need to know what time she actually goes on stage and begins performing. I know there is an opener. I have to wait for my friend to get out of work, and that isn't until the start of the showtime. I'm trying to figure out if that's ample time to get all the way over there from the Peninsula side and find parking without missing any of Adele's show.
