Hi,
i am talking about the "Build History" page of a Jenkins node, i.e.
http://your_jenkins/computer/your_node/builds

In Jenkins 1.457, there are 4 columns to be seen: "Build", "Time
since", "Status" and an icon with the link to the console output.
I wish there would also be a "Build time" column, so that we have the
information of how long the builds take on a given host/node.
Is there a rationale why this is currently not the case?

This would be a very simple fix in:

https://github.com/jenkinsci/jenkins/blob/master/core/src/main/resources/lib/hudson/buildListTable.jelly

at the line 47.

Thanks
