top output Time+ information misleading

Question

I am running SuSE 11.2. Shen I am running "top" command on one of my machine, it looks like this:

My question is why the Time+ value is so big? The machine has only been running for several minutes.

Answer 1

The time is caused by a large value set in the /etc/adjtime
