Machine learning model selection for Time Series problem

Dear All,

I am trying to apply machine learning algorithm to a dataset which consits of emission of pollutant gas from an engine called SO2(target variable) which is collected over 6 months of time for at a interval of each of 15 mins each.The dataset also do have other independent variables like pressure,vapour etc with time.
Now the question is
should i go for time series modelling like arima for forcasting the So2?
or should i go for randomforest or svm for forecasting?

Thanks ANd Regards
