next in thread | raw e-mail | index | archive | help
The ps output value for STARTED appears to be incorrect for
kernel started processes. I found this while writing a tiny ps
for our freebsd based network appliance. The start time returned
from /proc/{normal pid}/status (man procfs) appears to be in=20
UTC while the start time for a kernel process appears to be
localtime (or the other way round). This gave me wild values.
Is this correct behaviour ?
