Hi guys, Just found a issue when you change the state of your flow in UI, fx if a flow failed and you change the state to success. After you mark is as failed it would then get a new duration time, if you check my screenshot you can see the job finished 9:02 AM and marked it ass success around 53 minutes after and it got a new duration. If it isn't a bug, then please tell me why you chose this approach, thanks.

Hi @Dave - the UI is displaying the duration between when the flow started and when it ended (

start_time

 and 

end_time

 on the flow run object); if you need more granular control over what should be included to calculate metrics etc you might be better using task run or flow run state history. We're always open to how we might better give metrics and information so if you have ideas over how we might better show runtime, please do open a ticket for discussion in the UI repo. Also - would you mind moving the stack trace and image into this thread? It makes it easier for us to scroll through and see everyone's questions if the initial message is shorter. Thanks!

I'm running:

prefect diagnostics:
{
  "config_overrides": {},
  "env_vars": [],
  "system_information": {
    "platform": "Linux-5.4.0-1031-azure-x86_64-with-glibc2.29",
    "prefect_backend": "server",
    "prefect_version": "0.13.14",
    "python_version": "3.8.5"
  }
}

If you check the logs you can also see I marked it as success.

Thank you! 🚀

Gracias for the answer, I’ll do that next time 👏🏻 Having trouble with the image.
