A lot of people are making it out to be the new y2k, I read an article about that over the weekend. Forums no, not a big issue, but sites that involve money (amazon comes to mind)... Server logs that like to choke on time changes (they're rare, but they exist).

I do think that there are people out there that are making it a bigger mole-hill than it needs to be though ( I wasn't trying to be one of those when I said most of us would see it though, most likely as you said, we'll see it and say ok, have to fix that later). Oh and the Aussies did it last year too, they're just tweaking it this year.
