Better runtime performance? Have you even read the Phoronix article?
So there is just one, right? One lone article on Phoronix?
So from now on they’ll have the luxury of seeing a glimpse of the sun when they drive to work, yet they’ll have to resort to pitch black darkness when they get back. In summer, the sun will rise at 4 in the morning and it will be dark before nine in the evening. It won’t be long till there is a popular backlash against it – people will demand their DST back because they want their beauty sleep unimpeded by the overly early sunrise, and they want their evenings to be light longer.
At least that’s precisely what happened in my country when the government abolished DST for a couple of years. Plus there were ramifications regarding time differences with adjacent countries that had previously been in the same timezone. All in all, the experience that looked nice on paper (and I was initially for it) turned out horribly wrong. Even DST all year round (in effect moving the timezone one zone eastwards) is a saner approach, as long as humans are involved.
