Package: procps
Version: 1:3.2.7-5
Severity: normal


The start times of processes as reported by ps fluctuates 
occasionally.

The following command line shows differences in consecutive 
ps invocations, each 1 s apart. /proc/1721/stat field 19 
shows a constant start time of 6143 jiffies since boot for 
the mysqld process. The start time shown by ps fluctuates 
between 12:13:26 and 12:13:27 and the start times for 
(all?) other processes fluctuates by the same amount (1 s).

This bug may be related to the other time related bugs of 
ps.

Hi,
  This is a really old bug about ps start times.
There has been a lot of changes with hardware, kernels
and procps itself so I'm closing this bug.

If it does still occur on current systems, we can
reopen it or open another, but I'd say its fixed
due to the update of those three things.
