I hate DST. Well actually I hate the change of time.
First, my body works on it's own clock and even though I don't wear a watch, I'm pretty accurate at guessing what time it is. Except during the change.
But I'm also comfortable with modernity. I have some technology in my life. Digital clocks that each seem to require their own unique programing.
every car clock is differ't.
But my most annoying clock change is on a 55 year old Grandfather clock that has a special mechanism. When you correct it forward it speeds up to compensate. After a few days of correction, it is going the correct speed to keep good time. Works backwards as well.
But making a full one hour change put's it in schizophrenic mode and requires weeks of daily adjusting. Sucks because that is often the subconscious chiming that keeps my biological clock accurate. And it conflicts with the solar timing inputs.
I cannot imagine what the change does to animals.
