# Event Time in Data 360

An event date is a time-based attribute in a DMO that is defined at the data stream level during ingestion. A DMO can have multiple event dates. The Event Time Field applies only to DMOs designated with the Engagement category.

When a segment is processed, only records that have a value for all system date attribute fields are returned. When an Engagement DMO is included in a segment, the segment can process the data records up to 24 months of the event date field. A segment fails if the date range exceeds 24 months. To run the segment again, adjust the event dates to fit this range.

![Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-data-data_cloud-264-0-0-production-enus/f3569962-3c9b-4f83-9d0c-b6a574e785da/images/icon_example.png)

Example The Sales Order DMO designates the Purchase Date attribute as the event date field. When you use the Sales Order DMO to create a segment of individuals who made at least $500 of purchases within the past X days, the value of X can’t exceed 24 months.

Data federation sets up direct connectivity with data sources. It uses a zero copy integration that eliminates the need to ingest data into Data 360. During data ingestion, data is brought into Data 360 in its original form and stored in a data lake object (DLO).")
