black coffee and moose heads

Who came up with the idea of daylight savings time? Actually I don't need his/her name all I really want to know is why we went along with their brilliant idea. Please provide me with an answer, but don't tell me it is because of the farmers. Maybe that was the original plan but that answer will not work now. (I have nothing against farmers. Really they are great.Without them we wouldn't have food to eat but that is a story for another day). Thanks.
