Time is Relative
Recently I slept in three time zones in three days, being in Paris, France; Cleveland, Ohio; and Las Vegas. I expected the sun to set in Las Vegas at the same time I was used to in Paris the week before, or rather, twilight to end, at around 9:30 PM. The sun set earlier in Las Vegas. While the US is on daylight savings time while France is not, even aside from that the differences in daylight with respect to time are noticeable. Part of this is due to geographic variations. After all, Las Vegas is on California time, yet is further east then LA. Checking the data, here’s what I found for today: Paris sunset: 9:08 PM, Las Vegas sunset: 7:31 PM, Cleveland sunset: 8:27 PM. Quite a variance!
