The fact that most counties here in Indiana don't change their clocks twice a year is great if you are nothing more than a recluse. However, if you are involved in business, especially with customers out of state, you know the time change is a royal pain in the schedule.
I keep a small map of Indiana's counties on my desk and it is color coded by what time they observe. We talk in terms of being on "slow time" or "fast time". One of the reasons my employer moved its customer service center and accompanying 15 well-paying jobs from an economically depressed Indiana county to a neighboring state is because of all the semi-annual scheduling disruption and confusion from not being in synch with the rest of the region.
Many of Indiana's legislators are terrified of making the change because whiney farmers complain the sun doesn't come up early enough for them on DST and senile voters whine because they can't figure out how to change the time on their VCRs. Meanwhile, we lose lots of productivity in business because we have to ask ourselves, "What time is it there?"
To conclude the rant...if staying on Standard Time year 'round is such a great idea, why aren't 47 other states doing it too?
Personally, I don't need a chart, nor am I a recluse. I simply remember that after a certain date I am on Chicago time. Doesn't take rocket science.
So in other words, he was too stupid to do the math.
Cry me a river.
