Note that in this case it's conditional on Congress because Florida wants to move to permanent summer time, which, if we imagine that as of tomorrow DST were abolished everywhere else, would effectively put them in Nova Scotia's time zone ("Atlantic Time").

(I'm personally sympathetic; I live in the northeast US and I'd much rather go to work in the dark than leave work in the dark. Summer time or bust!)

In Maine we passed a bill to move to Atlantic time as well, but it's conditional on Massachusetts and New Hampshire moving to the same time zone: https://www.pressherald.com/2017/04/27/maine-may-switch-to-a...

(I would love this)
