Yeah, don't know about the poles -- been hearing talk about them flipping any minute now for the past 20 years so to me it's like flipping a coin... or not flipping it. Who knows.
As for daylight saving time, I like what a Native American chief said about it (quoting from memory): brilliant science -- take a blanket, cut a piece of it on one end, sew it onto the other end, and voila -- you now have a longer blanket.
People with small children and dogs are particularly 'excited' every time we switch the clocks... and us bazi readers hate it for an additional reason -- every time you do someone's chart you have to go check if DST was in effect that year, that month, that day at that location... ugh. It's different from year to year, country to country... and in the US, a couple of states don't switch and neither do some territories, but there's no guarantee they never did in the past when someone was born, so, still extra work even if it's a Zonie's* chart.
*Zonies are people who come on vacation to San Diego from Arizona. A local phenomenon.
