Subject: [PATCH 05/11] fix incorrect timeout while system time changed

While system time changed by NTP, invoking timeout_command
breaks with incorrect timeout.
--------
|05:40:55,872 INFO program: Running... mount -t ext2 -o
  defaults,ro /dev/sda2 /mnt/sysimage
|01:40:55,086 DEBUG program: 10 seconds timeout
--------

Use numbert count to replace current time count could workaround
the issue.

Upstream-Status: Pending
