I have a configured a cronjob in OpenShift. Its crontab entry looks like this:
spec: schedule: "0 3 * * 1-5" jobTemplate:
So it should run at 03:00 in the morning on weekdays. All cluster nodes are configured to use our local timezone, CET, which is UTC+1. This is visible via the
date command. OpenShift documentation says that cronjobs are executed via the crontab matching the configured time zone of the master nodes, so i expect the cronjobs to actually run at 03:00 CET.
However, according to the logs, the cronjobs are executed at 04:00 which is 03:00 CET in UTC. The strange part is that
oc describe cronjob reveals:
Last Schedule Time: Mon, 14 Jan 2019 04:00:00 +0100
So, the server actually knows that the cronjob is executed one hour too late.
My question is: Why is the cronjob executed one hour too late, why does the server know about it, and how can i fix this?
