Farmers, as a general statement (and please note where I live - I know plenty of them) want as much light as they can get as early in the day as possible. The phrase "up with the chickens" applies because chickens are up with the sunrise. For farmers, although strictly speaking the time on the clock doesn't matter to them, it is helpful when "the rest of the world" is on a time schedule that makes it easier for them to interact with that rest as necessary, and maximum overlap of waking hours occurs for "the two worlds" when standard time, not daylight time, is in effect.
There are also plenty of urban legends about standard time being necessary for "the children" when the school year gets in swing because so many of them have to be out at bus stops in the early morning hours and it's desirable that it not be dark when they are. But the fact is, standard time or daylight time, a very great many are at their respective bus stops well before the sun rises in the dead of winter. I was one of those many moons ago in Pennsylvania.
Time Zones were established for the transportation network of the time, the railroads, and Daylight Saving Time as an energy saving measure during the war years. It largely went away, for a while, after wartime was over but then came back.
Farmers and school children have never, ever, been the primary driving force behind time adjustments. This information is readily available from multiple reliable sources.
