Currently, the timestamp information is only provided directly by a few
Ansible modules (e.g. the command module, which shows the runtime of a
command per host result).
This change adds an 'overall' time information to all executed tasks. The
delta between both timestamps shows how long it took a task to finish
across all hosts/nodes.
Update: This information is now also available for plays.
This patch is also proposed for ansible and can be found here:
