|---|---|
| ### `timeWindows` | ` https://developers.google.com/ad-manager/api/reference/v202602/ForecastService.DateTime[]` The boundaries of time windows to configure time breakdown. By default, the time window of the forecasted [LineItem](https://developers.google.com/ad-manager/api/reference/v202602/ForecastService.LineItem) is assumed if none are explicitly specified in this field. But if set, at least two [DateTime](https://developers.google.com/ad-manager/api/reference/v202602/ForecastService.DateTime)s are needed to define the boundaries of minimally one time window. Also, the time boundaries are required to be in the same time zone, in strictly ascending order. <br /> |
| ### `targets` | ` https://developers.google.com/ad-manager/api/reference/v202602/ForecastService.ForecastBreakdownTarget[]` For each time window, these are the breakdown targets. If none specified, the targeting of the forecasted [LineItem](https://developers.google.com/ad-manager/api/reference/v202602/ForecastService.LineItem) is assumed. |
