Time Zones and Daylight Savings

I was once playing franchise as the chiefs and we played the raiders now anyone in new york time the game will start at 4:25 but in vegas the games starts at 1:25 once i got to third quarter the time changed then once i get to 4th quarter it got dark which isnt very realistic considering im playing in vegas so i think adding timezones will make a the game a bit more realistic cs lets say u the 49ers and u had a prime time game and its starts at 5:20 for anybody in new york eastern time it gonna start at 8:20 but at. 5:20 it should still be light outside well atleast till daylight savings
