Date change on reboot

2016-07-23 Thread Stephen Davies
My F22 randomly crashes to a frozen state that requires a power cycle to restart. When this happens, the time stamp on log files such as /var/log/messages changes for a while before reverting to the correct date and time. Today,the sequence was: Jul 24 10:55:55 mustang rsyslogd: [origin softwa

First thing I would check is the CMOS battery if you have one or can get to it. Sounds like system time is not being held. Go through boot log. If the system corrects shortly after a. Nts comes up and b. Network connection is established then this may be the case. Couple dollars for a button batter

Well - i hate to butt in here but i can most definitely say that my wristwatch for example most definitely indicates a dying battery by only moving the second hand every 2 seconds instead of 1 second - BUT it moves 2 increments each 2 seconds - but i have no idea if that has any relevance! > On

Back to square one. I have checked the battery and it seems fine and the hardware clock is correct. More recent reboots suggest that the "extra" log entries are from eight days before the reboot. There is nothing in the logs to suggest that the clock is being reset by ntp (though ntp is configu
