I think 12 would be fine (similar to Championship) but anything befor 12 is way out of line! Imagine travelling up to Newcastle for an 11am KO!
AZ has got it easy - he gets an extra hour in bed.
Burnley on a Sunday 11:30am KO will be splendid.
I was told during the summer Arizona is on the same time as California (Pacific Daylight Time is the same as Mountain Standard Time, the state of Arizona does not observe daylight saving time). So AZ does not get an extra hour until early November and that only lasts till early March.when California switches from Pacific Standard Time to Pacific Daylight Time. Arizona stays on Mountain Standard Time the whole year long.
