When I build a NetBSD release using a command like

  time -j 2 -d -D $build/destdir -R $build/release -T $build/tools -O $build/obj

on a dual AMD Athlon 1800 running a multiprocessor kernel, the output
from time(1) frequently has garbage in the user and/or system time
fields.  Here are two specimens:

    9051.58 real      4255.13 user -140461532.55 sys

    3970.16 real -1306333211.13 user -1446799052.29 sys

I have also seen similar garbage in the output from "ps -S".


See above.
