Time Keeps on Slippin…Slippin…Slippin into the…past?
Once again, I grabbed the title of the post from a play on words on lyrics from “Fly Like an Eagle” by the Steve Miller Band. For those of you who have no idea what I’m talking about, see this YouTube video, and know that you have made me feel very, very old.
The point to the title was that some of you may have noticed that calendar appointments, email time stamps and many other things seem to be off by 1 hour starting yesterday. The reason is that unless you have all your updates and hot fixes from Microsoft, Windows 2000 and 2003 would believe that Daylight Savings Time changes occurred on Sunday, October 25th at 2am, and changed the clocks on any non-updated servers. If that’s an Exchange Server, the incorrect change will flow over into all Exchange functions as well, causing quite a few problems.
Normally, we here in the US change our clocks twice per year. The latter one used to happen on the last Sunday of October, when we all set the clocks back by one hour at 2am on that day. The problem is that the US Government changed the rules late last year, changing the dates that these one-hour shifts take place on. This year, it will be November 1st, but Windows wasn’t originally programmed to deal with that.
Most of us update Windows and Exchange regularly, so we got all the appropriate patches and ran the required updaters on the systems in question. You’ll know you did it right if the clock did not change Sunday, and do change on November 1 at 2am. You know you missed at least one if either your server time, or your email time stamps are all an hour off today.
Yet another reason to patch regularly, but everyone can miss one now and then, so visit this Microsoft Support site on DST changes if things are acting odd time-wise. If thing are acting odd in other ways, throw me an email, I might do a column on it =)
