Hmm. That’s not how I'm reading this. *If* I’m understanding it properly (heh, heh), the names themselves are not changing; rather, it’s the *meaning* of the names that are changing, viz-a-viz:

Atlantic standard time: 	UTC-4 => UTC-3
eastern standard time: 	UTC-5 => UTC-4
central standard time: 	UTC-6 => UTC-5
mountain standard time:	UTC-7 => UTC-6
Pacific standard time: 	UTC-8 => UTC-7
Alaska standard time:	UTC-9 => UTC-8
Hawaii-Aleutian standard time:	UTC-10 => UTC-9
Samoa standard time:	UTC-11 => UTC-10
Chamorro standard time:	UTC+10 => UTC+9

So, despite all of the talk in the mainstream press about “permanent Daylight Saving Time”, this is actually a redefinition of *standard* time to one hour earlier than before, along with the *abolishment* of Daylight Saving Time.

Cheers!
