Sheduled automation executed twice with 2hrs difference

[Adrian Gaberell]

Hi

I created an automation rule to be executed at 9 a.m. every 10th of the month.
the crown expression is as follows:
0 0 9 10 * ?
today the autmation was executed 2x: 1st on 7 and 2nd on 9.

do you have an idea why this happens?

cheers, adrian

Hi @Adrian Gaberell 

the only thing I could imagine (even if this sounds quite unrealistic) is that the server timezone has been changed. 

As far as I know, the automation is executed based on the server time, so if you are running for example the server as GMT+2, the rule will execute at 7 UTC. If the time is then changed to UTC (for whatever reason), the rule would be executed at 9 UTC again.

Besides that, I am not aware of any reports for misbehaving cron jobs in Jira.

Did you observe this at another point in time? Or did you trigger the automation manually (maybe for testing purposes)?

Hope this helps!

Regards,

Stefan

Hi Stefan

There was no Timezone change in this time-period (7 - 9 am).
We had some problems 2 weeks ago with server-, application- and user-timezone.
Maybe Jira has an internal cache when the rule should be executed the next time and after the timezone-change the rule was marked for execution 2x?
