Time Derivative

The Time Derivative tool operates on a transient dataset. It computes the derivate (rate of change) from one time step in the dataset to the next. The resulting dataset will have n - 1 time steps for the n timesteps in the input dataset. The time associated with each time step in the resulting dataset is halfway between the times used to compute that time step. The tool supports an option of just computing a raw change in value, or a derivative by dividing that change by the time difference between the two input time steps. The user chooses the unit of time to use to divide. (Note: if the time steps in the input dataset have uniform temporal spacing, the change and derivative are just scaled versions of one another.)
