ID: 13739 Title: jenkins_nodes: Allow negative timespan for Clock difference Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The Clock difference of a Jenkins node can be negative if the node's time is running ahead. In this case the check would crash because negative values cannot be rendered as a timespan. Now the absolute value of the time is used and displayed.
