When running a search for syslogs within 7 days, Splunk is retuning some logs that are months old. Timestamp is correct in the event description (Linux Day, Month, Time) but the Splunk timestamp indicates the logs were within the 7 days search parameters. Other results within the same search are correctly returned, doesn't seem to be any pattern.
Check for where in the log the timestamp is. Often this occurs when the timestamp sometimes occurs farther into the log than the date time lookahead is set for.
Can you share some sample, sanitized events? Please also share the props.conf settings for the sourcetype.
Can I access the props.conf in Splunk Cloud? If so, how?
