Maritz's green gas stations generally have timeframes that ensure they'll get daytime photos, and they can be sticklers over this issue. I've done several CoRI gas audits, both revealed and unrevealed, in the dead of night and they were fine.
So long as it's a safe neighborhood, doing the audits that require photos of each pump can go much easier at night. I intentionally put a 16 pump location at the end of a route so that there's less traffic when getting those photos.
Just remember that when it hits midnight, it's technically "tomorrow" and you'll need an extension if it's your due date.
