Determines whether an action's date is reported based on the ad impression date or the actual conversion date. With action_report_time=impression, an action that occurred after a click is listed on the date the ad was seen; with action_report_time=conversion, it's listed on the date of conversion. For example, a conversion on Jan 4 from an Aug 3 impression would appear on Aug 3 with impression or Jan 4 with conversion.
