Changing time zones?

I heard an item on the news about New Brunswick deciding to extend Daylight Savings time to match the extension already announced by the United States. That didn't surprise me, but apparently at the same time the province was considering switching from the Atlantic to the Eastern time zone. That change was rejected, but the fact that they were considering it made me remember the recent talk about the state of Maine considering switching to the Atlantic time zone.

Wouldn't it be odd if Maine switched to Atlantic time zone and New Brunswick switched to the Eastern time zone? Ah, a time zone waltz. If the changes were enacted, going from New Hampshire to Maine to New Brunswick would mean bouncing back and forth through time zones. Actually, Maine switching to Atlantic time zone might actually make sense from a daylight perspective. Doesn't it seem like the northern part of the Eastern time zone covers a really large area?
