Attribute Question

I have two time series that I want to feed into a learning algorithm, probably start with a neural net or SVM. When I plot the time series, the gap or vertical space between the two lines is meaningful. However, should I make this an attribute? Or would the absolute position of each point be sufficient (the vertical space can be derived from absolute position)? Generally, how do I know when I should construct a synthetic / derived attribute?
