I like it when the US fucks with time zones. The more you fuck with time zones, the more likely US-based developers are to just say fuck it, we'll use a library. The more developers that use a library for time zones, the fewer pieces of software that I have to deal with that get this wrong for my part of the world.

(Did you know Australia has 11 possible time zones of which up to 9 are being used right now? It might even be 12. Most people don't, which is why most programmers fuck it up)
