It wouldn't work...
This whole concept is almost a paradox...
If Florida wanted the extra hour then they would need to change their clocks back and forward 4 times a year...
The logistics to make it work are so bizarre and not even worth it.
So imagine that instead of how you do it today where you move your clock an hour forward in the spring and an hour back in the fall, that you move it forward one hour in the spring and never change it again after that.
How is this so hard to understand?
So when it's 5 in Chicago and 6 in NYC those in Florida want it to be 5:30?
What about the other states that fall on that line? in one state it's 5:30, the next it's 5 and the next it's 6... That is unreasonable and highly confusing if you travel allot or live on a boarder.
If everyone else moves their clock twice a year - what makes you think Florida is so special from that?
Time is nothing more than a measurement - if we need to change our clocks twice a year - so does Florida otherwise they will fall back on time.
It doesn't work and the idea is stupid.
Seriously, what location does Florida have in our solar system that makes Florida able to change their clocks one time a year when every other geographical location changes it twice?
If I understand correctly, it works like this.
Date DST State Non DST State Spring 1 0300 0200 Fall 1 0200 0200 Spring 2 0300 0200 Fall 2 0200 0200 Spring 3 0300 0200 Fall 3 0200 0200
So for FL, it would just stay at 0300 rather than 0200.
I don't think it is possible to lose time. Time is linear and exists no matter how it is measured. The position of the sun is not really relevant. All the consequences of DST is to make it dark one hour later. There is some structural advantage to this in that "rush hour" would be in daylight so tired drivers would have a better chance of survival on their commute home.
