Drift Recorder Question

For the drift recorder, is the relative displacement the amount of displacement that occured during that time step or the cumulative displacement since the start of the analysis?

And is the displacement returned from the node recorder also the displacement that occured during that time step or the cumulative amount from the beginning?

Thanks in advance.

comulative -- the difference between the two nodal displacements divided by the specified length.
