Hi,

Wondering if anyone else is getting this wrong behaviour?

<apm -s OR echo 3 > /proc/acpi/sleep>
<resume after a while>
notebook:~ # date
Thu Mar 18 12:26:41 SAST 2004

notebook:~ # ps -ef|grep nothing
UID        PID  PPID  C STIME TTY          TIME CMD
root      2291  1550  0 12:24 pts/34   00:00:00 grep nothing

You can clearly see STIME column lagging behind the real system time by
2 minutes...

It seems to be behind exactly the amount of time that the notebook was
suspended for.

BTW, hwclock and system time is in sync.

I have tried recompiling with disabling HPET - made no difference. also
updated ps (rpm) to ps-2004.1.24-3, same story.  

Is ps broken or is this an obscure kernel issue?
