Sightings SRO: Do Observed_data_refs must be objects that occured within the Sightingâs first/last seen time range?

[Stephen Russett <stephen@digitalstate.ca>]

Following up on:Âhttps://github.com/oasis-tcs/cti-stix2/issues/159

A Sighting has a first_seen and last_seen time range.

The ObservedData objects that are applied in the Sighting's observed_data_refs also have first_observed and last_observed.

Are the Observed Data subject to the Sightings time frame?

Thanks
