I have 3 debian etch lxc's and they all show wrong dates in ps -ef

making a file time stamp is OK:
Code: 
# l> fo
# ls -l fo
-rw-r--r-- 1 root root 96 2017-09-21 09:08 fo


any clues on how to fix this?
 
What is date inside and outside of the container showing?
 
What is the uptime of the container & PVE? Also, does it return to normal after lxc reboot?
 
Code: 
sys10  ~ # pct exec 123 uptime
 12:26:41 up  3:55,  0 users,  load average: 0.35, 0.43, 0.52
sys10  ~ # uptime
 12:26:44 up 3 days, 22:31,  1 user,  load average: 0.35, 0.43, 0.52
I'll restart it now..

Is your ntpdate running inside the container? A lxc container cannot update the time and it would inherit the time from the host itself. This might influence the ps output in some way.
 
thanks, i noticed the same thing, then uninstalled ntpdate, rebooted. same issue. to be sure i just did a stop and start. date on ps -ef still in future
 
Is 'ps aux' showing the same start time/date? Could you test on a newer debian version, maybe there was/is a bug on etch?
 
we've a few stretch systems, time is OK.

on a jessie system there is an issue , i'll put info at end.

here is ps aux:
