Floodlight conversion time zones are now aligned with the client account's time zone instead of the product's (Campaign Manager 360) time zone. Clicks, cost and impressions also use the client account’s time zone. You set the time zone in the client account itself before the first sync into Search Ads 360. After the first sync, any time-zone changes that you make in the client account will be ignored by Search Ads 360.
If creating seasonality adjustments, the selected date or time is dependent on the view that you are in. Learn more about creating a seasonality adjustment event.
