How does summary indexing handle time?

I have noticed that when summarizing some events that do not have a timestamp (tabular reports, data from lookups), the _time value is not set as I would expect. How does summary indexing decide what time to use?

To set the time for summary index events, Splunk uses the following information, in this order of precedence:

  1. The _time value of the event being summarized
  2. The earliest (or minimum) time of the search
  3. The current system time (in the case of an "all time" search, where no "earliest" value is specified)

But when I try simple below query its taking the current system time instead of _time of event.

index=indexname | collect index=si

I want the events in the summary index to retain the _time as it is in the primary index. But it's storing the current system time.

I'm having the same issue. My events have a _time value, but it is not maintained in the summary index. It also stores the current system time which seems to contradict the precedence outlined above. Did you ever find a solution @AnilPujar?
