Extracting a column of data from a time series

Does anybody have any ideas as to how to split up the time and variable1 columns of a time series so that the variable1 data can be handled independently of the time?
I have created the two time series so that I could use the resample function to make sure the data in time series 1 is taken at the same time as the data in time series 2.
If it is not possible to extract just the variable1 column, does anyone know how to interpolate a column of data so that it contains measurements at the same times as another set of data, where the time is not evenly sampled and the data consist of a very high number of measurements?
One final query: does anybody know whether it is possible to find the gradient of a timeseries?

If you made a time series named 'position' for instance you can extract the data by doing: position_vector=position.Data;

In continuation with Kurt Stewart's answer. If you want the time as a separate column, use
time = position.Time;
