 CONT: The sky is still pitch black at 7:00 a.m. However, at 7:00  a.m. the next day, episode #4.24, it is very light and the sun is  clearly up. While sunrise times do vary slightly from day to day,  they only vary by that much on the day clocks are changed for  daylight savings time, and there is no indication given that this is  that day.
