@jef Quite right. Changing the clocks forwards or backwards achieves nothing; each day has still the same number of hours of daylight or darkness, regardless of when bureaucrats deem 0900 to be.
The changing started so that capitalists could wring more out of their workforces; it was nothing to do with road safety!
Regulate the clocks by UTC; adjust for your position on the planet.

Changing time wastes time.
