We've just been dragged through the absurdity of changing the clocks - Spring forward; Fall back - and I had to wander about the house and my car changing the hours hand. My antient but serviceable phone needs to be told what the time is although yours almost certainly can work things out for itself - that's why it's called a smart-phone. Making things easier makes the brain less resilient: computers remember passwords so we forget them; direct debits and tappable cards make it easier to separate us from our money; sustained research gets onerous because of Google . . .
I've ranted about the clock-changes before and there indicated the real cost ($400 million/year in the USA) of tricking about with
our bioclocks: heart attacks, road-traffic accidents
and work-clocks: missed appointments and flights, lower productivity.
So there is a distinct advantage to staying in the same time-zone all year.
None of my business, of course, my only locus standi wrt Indiana is that my sister worked for a few years at Indiana University Press and we went to visit with her in Bloomington IN a couple of times. Bloomington is a lovely University town which punches way above its population for Arts and Culture. That was one of the reasons why writer Bill Bryson washed up in Dartmouth NH, another university town, when he returned to America after decades in England.
If you look carefully at the US time zone map you'll see that Indiana (identified with a large blue arrow) mostly follows Eastern Standard Time but there are two enclaves of Central Time at the top left and bottom left of the state. This is made a teeny bit clearer if we look at the timeline for timezone change over the last 100 years:
Red L] which scrapes together a million people. Chicagoland is about 8x bigger. The circular gestalt of IlInKy3 suggests why it shares a timezone. It is within the signal of several TV stations: no better reason than that everyone can tune into 'Friends' at the same clock-time. Then there is the fraught issue of DST, which Indiana was notoriously against for many decades: they called it Fast Time. Possibly in reference to the fact that if time ran too fast, the straw would be ripped out of the corn-farmers' mouths and their John Deere hats wouldn't stay on straight.
We thus see that one of the great existential questions of our day is
"What time is it in Indiana?"If you know please answer on a postcard.
