Yes, apparently, this is often requested feature.
I dislike the copying of the existing code, sincere up to the comment
that is not quite relevant (about interrupts in systime). I slightly
reorganized the patch to reduce the copy/paste part of it.
Do you have comments ?

Try applying the attached patch to ps. I've had it for a while but never
submitted a PR.
Heh. I've had it for a very long time.

Maybe:
ps axwwwo pid,time,command
According to ps(1):
time ... "accumulated cpu time, user + system"
Unfortunately, I'm not able to find a way to get user time separate from
system time ("time" -- aka "cputime" -- only gives combined "user" plus
"system" time).
