No. the seconds in 00:00 is a rounded value. Many processes use small amounts of CPU time, less than 1 ms. And yes it is parent + all children.

We are on a fast HPUX PA_RISC box. Most processes show 00:00 because they use a tiny amount of CPU time.
Code:
jmcnama  3002  2993  0 08:29:57 ?         0:00 sshd: jmcnama@pts/0
 jmcnama 11290  3005  1 10:13:53 pts/0     0:00 grep jmc
    root  2993  2175  0 08:29:51 ?         0:00 sshd: jmcnama [priv]
 jmcnama  3005  3002  0 08:29:57 pts/0     0:00 -ksh
 jmcnama  8732     1  0  Apr 29  ?         0:07 uzpletd a b
 jmcnama 11289  3005  2 10:13:53 pts/0     0:00 ps -ef

uzpletd is a daemon running in test mode for 14 days. All the other processes show 00:00.

PTS_QUIT(1)						       AFS Command Reference						       PTS_QUIT(1)

NAME
pts_quit - Exit from pts interactive mode SYNOPSIS
pts quit [-cell] <cell name> [-noauth] [-localauth] [-force] pts q [-c] <cell name> [-n] [-l] [-f] DESCRIPTION
The pts quit command exits from pts interactive mode. The command can be run from the command line or interactively, but on the command line it does nothing and is therefore of questionable utility. CAUTIONS
Prior to OpenAFS 1.4.5 and OpenAFS 1.5.23, the pts quit command was only available on Unix or Linux and when OpenAFS was compiled with the supergroups option (disabled by default). As of OpenAFS 1.4.5 and 1.5.23, it is always available. OPTIONS
Although they have no effect, pts quit takes the following standard pts options: -cell <cell name> Names the cell in which to run the command. For more details, see pts(1). -force Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the first error. -help Prints the online help for this command. All other valid options are ignored. -localauth Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or -noauth options. For more details, see pts(1). -noauth Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1). OUTPUT
This command produces no output. EXAMPLES
Here is an example of a pts interactive session: % pts interactive pts> quit % SEE ALSO
