How Time Works in Elasticsearch (Explained in 90 Seconds)

Sep 9, 2025

Time in Elasticsearch is more than a timestamp; it's a powerful lens. In this 90-second guide, see how Elasticsearch lets you bucket logs by minute, hour, day, or even millisecond. You can zoom out to see patterns or zoom in to investigate exact spikes, all without recalculating.

00:00 Time isn’t just a field, it’s a lens

00:12 Bucket by year, month, day, hour, second, millisecond

00:28 Zoom in: find the moment something happened

00:42 Zoom out: see the pattern across days or users

00:55 Example: traffic spike at 2:00 PM, broken down

01:10 Time lets you slice data like humans think
