"Forecasting is the art of saying what will happen and the explaning why it did not" forecast is objective as well as subjective about the future based on specific assumption the ultimate objective of time series models is to use then for forecasting purpose. In general forecasting involves risks due to forecast error and these forecasts error depend on the forecast lead time. The lead time is the gap between time to be forecast and the time used as origin to make forecast.
