Let me start off by saying that I enjoy DST more than Standard time because the sun more closely resembles my ideal sleep pattern.
Apart from that, it has been hectic for some people where I work. Dealing with computers that weren't updated, interacting with those that were, have caused some headaches for people. I find it interesting that our group got everything up to date but others fell short on just 2 days notice that things wouldn't perform as advertised because of the change over.
I guess I'm proud to be thorough at what I do.
