Why are we seeing logs from year ago even we use sumarriesonly=t
| tstats summariesonly=t earliest(_time) as EarliestDateEpoch from datamodel=Authentication where earliest=-8mon
| eval EarliestDate=strftime(EarliestDateEpoch,"%m-%d-%Y")
Even the summary range = 1month, i just want to get the earliest date of the summaries.
