Read “A Man of Shadows” by Jeff Noon to see how difficult things are when people disagree on what the time is.
I could but I am not sure of the relevance.
The question I was asking is why, bearing in mind most of the world doesnt adjust times and that those countries which do dont necessarily do it in sync with us, would it cause problems globally.
Sure be a bit of an arse updating systems to remove the check but nothing overly difficult. From experience the adjustment leads to more confusion when working with Asia when suddenly some meeting times start getting rejected.
Given the evidence of accidents etc there is a strong case to drop it vs an unclear case in its defence.
