Definately has to be a time-change problem. I had this issue tonite just while browsing web. SystemUIServer jumped to 90%+ cpu and I wondered what was going on. I rebooted and that didn't work. After reboot launchd, syslogd and SystemUIServer combined were consuming 100%. After finding this thread, I messed with the computer date (changed to Nov. 2) and turned off the automatic time update and cpu dropped to >5%.

Even if Apple were to get a patch out within the next few hours, the Daylight Savings bug will have passed... anyone who was AFK between midnight and 1am will likely never even notice the bug.
Hopefully this doesn't crop up again next spring with DST rolls around again...

I had the same ******** problem. Fixed by taking the clock off like you did, or manually changing the date/time worked as well.

Its a weird issue, but I have to strongly disagree with you on Snow Leopard being bad. Some people will always have issues, that will never change. All our machines run quite well on SL, and we have not had any issues at all, and we have over 34 MacBooks and Mac Pros running.
Bummer that you seem to have issues, but that's a minority.

Must be Daylight Savings bug. Just hide the menu bar clock to "fix" it temporarily.

"Bummer that you seem to have issues, but that's a minority."
We're all here in a thread talking about our computers freaking out because THE TIME CHANGED. If it was Windows doing this, Macintosh fans would chalk it up to MS's incompetence once again. And anyone who's seen the list of bug fixes for 10.6.2, combined with the fact that a lot of major hardware at work no longer works with my computer ... no, this is Apple's Vista.
I wonder if Apple will even acknowledge this happened.

I can verify on this too. I wondered why my CPU was acting insane (it started about an hour ago). I searched all over the net for SystemUIserver high CPU usage info, tried everything I could find, found this thread (Google acts fast), disabled showing the time in my menubar, and now everything is fine.
How can a DST change mess something up so profoundly?

Isn't it ironic that just as daylight savings time kicked in, power consumption of all Macs went boom?

i don't think i would say that SL it horrible just because your fan spins up for a half an hour right before DST change, i'm sure this is a small bug that will be fixed before the time changes again. all operating systems have bugs when they first come out. this problem is nothing compared to what i went through when first upgrading to vista. os x in not perfect but it's a lot closer than windows.

Me too. I thought it was the new Bamboo Wacom Pen Touch I installed, but as soon as I turned off the date and time, my CPU usage went back to normal. Waiting for the fix!
