HI @Ashay Jain 

Are you referring to alerts from a individual chart via alert monitoring?

If yes,then I don’t think you can set any specific time since alerts will be triggered whenever your alert condition gets triggered.

However, if you are referring to dashboard reports subscriptions, then you have the ability to control what time and day you want those recurring reports.

Hope this helps.

Thanks Saish for responding back. I am referring to alerts from an individual chart via alert monitoring. 
I was trying to restrict alerts from 6am-10pm as my alerts were not statistically significant during night time. 

Yea, don’t think that’s possible for now. Maybe you can key in a more restrictive condition trigger on your alert settings to achieve statistical significance.
