linux top command shows odd value in TIME+ column
 
I run top and sort by TIME+ column. Notice that the first process' TIME+ has an odd format.
That large value shows up the moment I run this program and never changes. Is this a bug in top.

# top -version
top: procps version 3.2.8

Maybe the process hangs and since it doesn't use the CPU, the CPU time doesn't change.

I'm using it so it definitely not hung. 71571 hours is much more than the machine's uptime of 5 days. And that value shows up as soon as the process starts.

That should be 71571 minutes!
64:48.26 -> 64 minutes, 48 seconds and 26 hundredths of a second.

Not hung (I used the wrong word) but even if in a sleeping or waiting status, the point is that it doesn't use the CPU so the TIME count is not increased. The TIME column shows the CPU time, not the elapsed time.

You right 71571 minutes, which is over 49 days, and uptime is less than 6 days. So my point is even if the process had run at 100% cpu since up, this number would still have to be much smaller.
