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.
