On April 29, after Agent Benford punches out Helinger and is subsequently thrown out of the building. A little later there is an overhead shot of LA at night with a caption saying it is 6:38 PM. Agent Benford is then shown on the street in LA surrounded by people partying and it is nighttime. Sunset on April 29 in LA is an hour later at 7:35 PM. So it would not be nighttime, there would actually be plenty of daylight.
