>Description:
The "TIME" column in ps's output is specified by IEEE Std 1003.2-1992, and
by IEEE Std 1003.1-2001 as containing:
# [dd-]hh:mm:ss
#
# where dd shall represent the number of days, hh the number of hours, mm
# the number of minutes, and ss the number of seconds. The dd field shall be
# a decimal integer. The hh, mm, and ss fields shall be two-digit decimal
# integers padded on the left with zeros.
<http://www.opengroup.org/onlinepubs/007904975/utilities/ps.html>
On NetBSD, though, the format appears to be hh:mm.ss, with hh not being
fixed-width

Hi,
the attached patches should solve that issue.
Though there's one issue: This patch introduces POSIX compliancy, but
decreases precision. Before, you had the cputime measured in centiseconds,
while POSIX requires it to be at most seconds.
You could either introduce another keyword - e.g. pcputime or ptime (p for
precision) to display them again - or dump this proposal and be non-posix
compliant or dump the precision and be posix-compliant.
Which is the way to go?
Regards, Julian

Imo it would make most sense to keep the traditional display if
called with BSD syntax ("ps ax"), and be POSIX compliant if
called with SYSV/POSIX syntax ("ps -ef").
As long as we don't support POSIX at the command line there is
no need to have the display strictly POSIX compliant.

Matthias

ok, so what about the attached patches?
They have [[dd-]hh:]mm:ss for etime in any case, [hh:]mm:ss for time in POSIX
case and [hh:]mm:ss.pp for time in BSD case.

Where are POSIX-style options and BSD-style options defined?
I don't mind adding days, like "[ddd-]HH:MM:SS.ss", maybe even
breaking compatibility for scripts that parse the output from ps,
but why do we have to be compatible with a stupid POSIX rule about
"no fractional seconds"?
Looking at the implemetation, it appears that the output from "ps
ax" and "ps -ax" will be different. I really dislike this. If we
do any sort of magic format switching, then I'd like a better way,
and whatever we do the man page should contain a discussion of the
tradeoffs.

Since POSIX chose to bless System V ps and we have a Berkeley ps,
there's not much point in expecting (or attempting to implement) exact
conformance.
If there's a real reason to want a System V ps (as opposed to
standards wanking) it should be a separate binary. Otherwise you end
up with horrors like linux's procps.

I've suggested using _CS_PATH for this before, _if_ someone really
cares sufficiently about having a System-V-ps-done-right in the
system to implement it.

State-Changed-Why:
System V ps considered harmful to sanity. If someone wants it badly enough
to implement it properly, let's do so; in the meantime, there's no point
worrying about this issue.
