These are info-level logs. You should not worry about them unless you're trying to chase an issue you've observed otherwise. Cheers Sebastian

Hi,
I just wondering, it is a bug?
Regards,
AFAIK, there is no bug. I used to see this message when I was behind a router with wrong UTC summer/winter time configuration. Now I don't see them anymore. Are you sure your time zone settings are properly configured? Regards,
Hi, My zone it's correct, when I will have a wrong time the NTP Pool will "out" me from the pool. http://www.pool.ntp.org/user/drixter The same machine, where relay is running.

It isn't a bug, but it is not great that some Tor relays have the wrong time. But so long as they aren't *too* wrong, it isn't the end of the world. I just counted them up, and I think there are about 30 relays with wrong clocks, out of the 6000 or so total. That's pretty good. I think those relays are probably seeing complaints in their logs, since while you see those at info-level because they're not directory authorities, when you notice that a directory authority disagrees with your clock, it's logged at warn-level severity. I wonder how to get them to notice more consistently? --Roger

Simple, either mail their contact (if any) and they fix it, or blacklist their fingerprints. There is no reason any relay should not be able to sync time.

Other possibilities: - extend the Tor Weather service to detect this and send mail - assign a flag (i.e. "BadClock") when the clock is way out of sync Using the contact info wouldn't work for me personally, since I didn't put a machine-readable email address in there. Best regards, Alexander
Hi, +1 from me for the flag If the time issues really make a problems in tor network.
