Dear,

On our platform, we have 3 jenkins instances based on the LTS 1.596.1

On each of these 3 jenkins instances, I have created a free-style job which is periodically executed each 2 minutes. This job does nothing else (no checkout from a repository, no maven build, etc - this is the more basic job which can be done)

On the first 2 jenkins instances, the job is well executed every 2 minutes.
However, on the third one, it is randomly executed (more or less every 20 minutes).
This makes me think that I have a configuration issue on my third jenkins instance.

On 27/03, I have added some logs in the Jenkins administration panel and found the following stack trace:

cron checking 3/27/15 4:49 AM

whereas the date on the server was different:

[www@MYSERVER ~]$ date
Fri Mar 27 10:32:27 CET 2015

In order to allow me to investigate on this issue and identify the difference between my 3 servers, I would need to know if there is a configuration file or a specific directory which manages the date of the jenkins crontab.
Could you please explain how the cron process works inside Jenkins ?

Please note that our Jenkins instances use:
user.timezone=Europe/Paris

Best regards
