Wired News: Spring Forward and Miss a Meeting:
Currently, most Indiana computer users set their PCs to a special “Indiana East” setting -- Eastern time that doesn't spring forward every April. Starting this April, however, they'll change their PCs to Eastern Daylight Time. The few who observe Central time set their computers to Central, and will also make the switch.
Most of Indiana is on Eastern time in the winter, except for a little corner of it just south of Chicago that's on Central. But in the summer all hell breaks lose. Or broke, is it turns out. Because this year will be different. This year they'll observe a state-wide DST, whereas in the past it's been a sort of local option thing.
So it transpired, in past years, that a city like South Bend, for example, would be on the same time as New York in the winter but the same time as Chicago in the summer. (And to complicate matters further the sun, in South Bend, is always on Chicago time.) People who live just north of South Bend, as I used to, in Southwestern Michigan, were on the same time as South Bend in the winter but an hour earlier in the summer, which meant that for business meetings in South Bend one was
always either an hour early or an hour late. And it was entirely possible - indeed likely in some parts of Indiana - to live for part of the year in one time zone and work in another, all without ever leaving the state. And for the other part not.
So this year's switch to state-wide DST, while it may make things more difficult for the computers, should make things markedly easier for the people, assuming they don't get too confused by being un-confused.
I don't want to think, though, about the cows.
