clock skew?

Has something strange happened to the clock on the forums host? I am being shown as having visited about a day in the future, and this makes the "posts since last visit" feature unusable.

Yes, there was a <cough> problem <cough> with the server. We jumped ~ 84,000 seconds in to the future. So, I took us back 84,000 seconds, and here we sit, some minor stuff br0ke for a about 22 hours.

If that's all you noticed you are lucky. The forums have this "anti-flood" feature, and if you post within 10 seconds of your last post it complains. Well when I flipped the time back, 181 (exactly --

) users had posted about 23 hours in the future and couldn't post anymore.

Oh well, a few mysql queries fixed all that. I think that changing the post times back would be more trouble then it is worth -- in 24 hours it will be fine.

Aren't you using NTP?

I wondered what happened...

I'd like to see the thread with a problem fixed before it was posted

Yup, but the system clock was too far off to sync via ntp. Power died at the datacenter... system clock wasn't in sync, and was too far off for ntp to work.

ntpdate won't help you either?

That's what I used to correct it, but I had to use it with the -b switch, because the clock was too far off.

Maybe the ntp init script could use ntpdate -b... I've had to use it before too (the clock was off by a whole year, silly people) and I think in most cases timeservers can be trusted.

Yup, yesterday I updated the ntpd init script and commited it. All new emerges of ntp will include it.

Save the rest of the Gentoo world from running in to a preventable problem.

Naturally, AFTER I've emerged ntp. No big deal, I haven't figured it out yet.

Just in case anyone else has a problem with Daylight Savings Time,
be sure /etc/localtime is linked to the correct file in /usr/share/zoneinfo/
