This morning, checking the "Manage Jenkins" page, it said: "Some projects have builds whose timestamps are inconsistent. These will confuse Jenkins when it tries to look up build records." There is a link to http://jenkins-ci.org/issue/18289.
What happened is that the clocks went back (end of summer time), which means jobs scheduled in the "duplicated" hour ran twice, and some of the later runs were at an earlier wall-clock time than the previous. Hence Jenkins gets confused. It's not a big problem for us (it might be more of a problem for others), but any suggestions as to how to handle this in future? Should this be considered a Jenkins bug? I added a comment about this case to https://issues.jenkins-ci.org/browse/JENKINS-22106 "@midnight is vulnerable to DST witching hours" Matthew -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.
