Actually indextime has a WONDERFUL, very security relevant use case and that's for events with potentially delayed data. A great example is EDR data; if a user is off network for awhile and the agent can't report, when they do finally log on, their events may flow in with the proper timestamps for when the event occurred *however* because we are running our detections on our most recent events, detections will completely miss these. In almost every other case, I'd recommend normal _time. But _indextime is very useful for this usecase. Also can be handy with RBA so notables don't fire as events from the beginning of the time window roll off the detection window despite having already fired a notable and APPEAR unique but throttling can't account for; explained here - https://splunk.github.io/rba/searches/deduplicate_notables/#method-ii
