If you’ve worked with Splunk for a little while then you are probably familiar with the existence of the field _time. With Splunk being a time series data store, it makes sense that every event will have a time. Internally, Splunk parses the timestamp from your event and converts it to epoch (seconds since Jan 1 1970 00:00:00 UTC). When you use your time range picker to select a time range, that is also converted internally to epoch and used to control what data is searched.
