Inside lxc containers, /proc/uptime is the uptime of the container rather than of the host system. However in /proc/[PID]/stat, starttime is the time since system boot, of the host system, not since the container started. This leads to emacs computing incorrect values for start, etime, and pcpu for processes. I think it should get the boot time from "btime" in /proc/stat, this is what ps does, which shows correct times for processes inside the container.
