 				<t>An implementer of a passive DNS Server MAY chose to either return time_first and time_last OR return zone_time_first and zone_time_last. In pseudocode: (time_first AND time_last) OR (zone_time_first AND zone_time_last). In this case, zone_time_{first,last} replace the time_{first,last} fields. However, this is not encouraged since it might be confusing for parsers who will expect the mandatory fields time_{first,last}. See: <xref target="github_issue_17"/></t>
