Since Hawaii is in the middle of a plate, not just the middle of the ocean, there are few neighbors to worry about. A more apposite example might be locales on either side of the mid-Atlantic rift - neighbors who are rushing apart in geological terms. I suspect that we could all reach consensus that if some nation is physically transported into a different timezone that it is appropriate for their clocks to reflect this fact :-)
