Cron Trigger works on and off

[Ohad Cohen]

Hi All,

I'm using the declarative pipeline approach and when ever i use: properties([pipelineTriggers([cron('H(0-0) 00 * * 2,3,4,5,6')])])

I can't really be sure when will it trigger, it sometime do and sometimes don't.

I'm using the "Next Executions" plugin (https://wiki.jenkins-ci.org/display/JENKINS/Next+Executions) 

and it says that the pipeline should be active at the desired time but when that time actually comes it ain't.

Does anyone know about a solution for this problem? (Jenkins Ver 2.51)
