No, but other than a lower limit of the process start time it has no
correlation whatsoever to the start time of a process that I am not
proviledged to get the start time from.

System processes get started and re-started all the time, as do
processes from other users (interactive or otherwise).

So again: in the case under discussion we _know_ that "0" is a bogus
timestamp value that no process ever got started on, even if it can be
translated to "Jan 1st 1970" if it were indeed a valid timestamp.  All
I'm asking is that ps shows something like "N/A" instead of trying to
print something that looks like it might be a valid time, but still
isn't.

Achim.
