While trying to implement daylight saving time during the early days here in the islands, there was quite the confusion when the western missionaries tried to explain to the natives to "fall back" when the October moon was at it's fullest.
This led to head trauma in such massive numbers that the Royal Court declared Daylight Saving Time "kapu" forever. This is the reason that Hawaii does not observe this "mainland" tradition.
When this event was told to other neighboring islanders, they immediately followed the lead of the Hawaiian king. American Samoa, Guam, Puerto Rico, the Virgin Islands also refused to observe Daylight Saving Time.
This story slowly reached the western shores with the returning missionaries. When they spoke of the horror that took place that October eve the territories known today as Indiana and Arizona followed Hawaii's lead.
After many hours around the campfire sharing firewater and the peace pipe, the Navajo Indian Chief and his son apparently misunderstood the delegation sent from the Arizona Territory, because to this day, they are the only ones in Arizona that observe Daylight Saving Time.
