Most of the world is the voice of reason actually.

This is a very European / North American problem for some reason. There are some exceptions, but in general Asia, Africa and South America don't do this.

If you mean "changing time in summer", Chile has been doing this for a while, and I think other countries in South America do to.

If you mean "changing the rules a few hours / days before they should be applied", Chile (again) did this a few years / decades ago, and it wreaked havoc: all scheduled meetings were off by one or two hours, you could not rely on your calendar, etc.

Plenty of stupidity going around in Chile / South America, rest assured.
