Alerts - time delay

I know that CJA has an option in the alerts to delay them, but I'm not sure if the specifics about how setting it up works. AA doesn't have the same delay option though.

But there is a workaround. When building out the alerts, you can add segments to limit under what conditions the alerts fire. You can use the "hour of day" dimension in a segment, and then use that to limit when the alert fires. 

For example, a previous company I was at had a problem with alerts firing false positives overnight, so we made a segment that said hour of day equals, and then we put all the hours between 6am and 10pm. That prevented the alert from firing between 11pm and 5am.

So for your use case, if you want the alert to only fire in the afternoon, you can build a segment using 'hour of day' and put in 2pm, 3pm, 4pm, etc. You can set the alert granularity to hourly and then on the hours you've indicated it will check the conditions of the alert and potentially fire. But you won't end up with the alert firing at other times of the day.

So it's not a delay per se, it's more of a workaround. But it should do what you need.
