I have a lot of movement data from a sensor of an android phone. The sensor-data is not equally spaced. The first column is the timestamp, the second to fourth are the values.

What do I have to do, to get equally spaced timestamps and according sensor-values. Matlab or python aren't an option.
EDIT: So if ever someone finds this in the future and needs the answer... I used this method to interpolate. The step-width I used to interpolate is the one difference in these timestamps, which came up the most.
