It's supposed to be 6:30 but they often do it early. Last time I was there they did it at 540 so I would call them ahead of time and explain your situation and they're pretty great at that location and will probably work with you but if you're planning on getting it out that day and you don't get there until just 10 15 minutes before the time then it won't go out that day
I think it is between 6:30 and 7:00 pm
