Does anyone know of a predictive model that can combine the linear regression model and time series model?

I have some data about some products. The data has two parts, some attributes about the products themselves, and some time series data of month-by-month sales amounts for each product. We want to predict future month-by-month sales amount for each product. with the products attributes data, we can build a regression model, or an svm model, to predict sales amounts. With the time series sales amount, we can build a time series model to predict sales amount, but is there any predictive model that can combine the regression, svm, and time series models to do the prediction?

You can use time as an additional attribute of the data. If you are having monthly data then your time feature could have 12 different values from 0 to 11. If you are having quarterly data your time attribute could have 4 different value from 0 to 3. You can refer Forecasting: Principles and Practice for more clarification. It's a good book.
