Sorry for not seeing your reply in time
Your patch doesn't seem to fix the problem. The root cause of the problem is that
the "vtime->utime" and "delta" are temporarily added to the stack and show to the user.
I tried to submit a patch to avoid presenting time backwards to the user. as bellow:

Hope you have better suggestions, thank you for your reply.
