date in binary and messages differ one day

Michael Schulte zur Sur — Mon, 13 Jun 2005 08:16:33 GMT

Hi all,

I have noticed that the date in the binary errorlog and the messages differ excatly one day for one speficic event. How can that be?
The os is 5.1B pk4.

Thanks for any idea,

Michael

What is the specific event - can you post an example?

What error log reporting tool are you using (uerf, decevent, sea...)?

If the specific event is regarding an external controller, like an HSZ80, the date on the external controller could be wrong.

More date (umm, I mean, data) is needed.

Stuart,
thanks for answering. I used decevent for analyzing. Both refer to a boot.

The correct date is Jun 11th because on that Saturday I booted the machine after a planned outage of a few hours.

That's a weird one, alright.

The boot message in the error log shows 10-Jun, and this is the system date at the time of the boot.

The syslog messages shows 11-Jun.

Therefore, the system time changed between boot time and when syslog started logging messages.

The default order of startup is syslogd, binlogd, some network stuff, then the time setter and the time daemon.

Is it possible that the order of startups have changed, such that syslog starts after the time setting/daemon? I suppose that it's also possible that syslogd started up, and took a little while to actually "get going", and that the time setter ran during that interval.

Of course, that doesn't explain why the system time at boot was 10-Jun.

When was the shutdown? Do the error log and syslog messages indicate anything out of the ordinary?

The shutdown was a planned one and occurred round 6am on Jun 11th. There were no out of the ordinary messages at that time. The sequence of events, you mentioned, is the same. So I still do not have a clue!

Thanks,

Michael

Did you finally get a fix for this one ?

Ronald,

thanks for posting but the problem is a mystery to us.

greetings,

This is a known problem with DECevent. It displays dates as one day early. Any other utility will display the correct date. I would recommend using WEBES.

Han,
I can't believe this has eluded me so long.

Ronald,
thanks to you this thread got once more attention.
