Lookup data from the last == ingestion_time()

Hello!
When you specify "Lookup data from the last X hours/days", Sentinel applies the filter on TimeGenerated, meaning it looks for logs where
TimeGenerated >= ago(X hours/days etc)
This ensures that the rule evaluates events based on when they actually occurred, not when they were ingested.
Thanks for the reply! This is interesting. Are you sure about this? Im finding some of the TimeGenerated to be unreliable and all over the place. For example events having TimeGenerated after they are ingested (time paradox)
Microsoft product unreliable? No way :D
