And what does Arizona do?
And Hawaii.
“And what does Arizona do?”
Arizona keeps Standard time the year round. The sun comes up anywhere from 5 AM to 7:30 AM, depending on the season.
However, the Federal national parks (Grand Canyon) and Indian Reservations (Navajo, etc.) usually stick to Federal time, meaning, that they DO have daylight savings time.
This creates complications when you are told when to arrive at the Grand Canyon, and you are going by Arizona time instead of Federal time.
