Its funny how many of my house appliances and cars and such just have the Daylight Savings Time hardcoded. It's going to be a pain, because not only will they not change this weekend, but they will change in a month or two. I've heard a little press about the change, but it will cause outages and issues. It will not be the non-issue that year 2000 was when it happened.
As for my company, it has been in planning at our company since August 2006, but it wasn't seriously engaged until January 2007. We've been frantic trying to get things fixed in time. We have done as much as we can, so we'll see how it affects us.
If we had better auditing, and deployment tools this would have been a lot easier to manage. I am hoping that this gives me and ammunition that I need to convince people to start taking this more seriously. We will start a larger Opsware SAS pilot once DST has passed, and we've fixed those issues which popped up.
