    Summary

    Complex Extension: A date/time value that is determined based on a duration offset from a target event.

    • target: Reference: The event that the date/time value is relative to.
    • targetPath: string: The path to the element that defines the effective period for the event that the date/time value is relative to.
    • relationship: code: The relationship to the effective period of the target event that the date/time value is relative to.
    • offset: Duration, Range: A duration or range of durations that specifies the offset between the date/time value and the target event. For example, 30-60 minutes before.
