Scheduled action running consistently late

I have an action configured like

    - cron: "00 03 * * *"

name: my workflow


I expect it to run daily at 03:00 UTC, or on manual triggers. However, it’s been getting triggered a few minutes late, every day – in the actions page for that workflow, it says it’s been running at around 03:14 UTC every day.

Is there something wrong with the config?


This seems to be a fact of life with regard to scheduled jobs. Further I’ve discovered that there is some unpublished window within which if they haven’t run they get skipped :frowning:


This is alarming. Between this and the workflow concurrency issue I ran into this week, it undermines GA as a CI and dev workflow replacement. I’m hopeful that both of these issues are growing pains and will get resolution.

Most of the time, there is a delay when triggering the scheduled workflow. This is a legacy issue.

Earlier, we had reported this issue to the appropriate engineering team for further investigation and evaluation.

Thanks for that info, @brightran. I think that it is probably reasonable that issues exist, though the request is that the behavior at least be documented.

For example, a note should appear in the on.schedule documentation.

Is there any update on whether it’s something that will get worked on and improved and, if so, an expected date for that to happen?

:slight_smile: GitHub recently announced that they’ve Open Sourced their documentation, so you could open a PR and suggest an edit:
