Daylight saving is bad bad bad.
The cows don't like it. They gotta get up an hour earlier for milking.
The extra daylight and sunshine means that people use more power in air conditioning. Power sources are stretched as it is.
It increases the effects of global warming, due to that extra hour of sunshine on the planet.
When I lived in Adelaide the paint peeled off the walls. and that was all contributed by DLS. That extra sunshine is unnatural to the environment.
Above all that why would astro people want an hour less of dark skies??
