+#### Parameter timeseries
+
+If the index provider contains parameters that change during the course of the simulation
+at discrete time points, it must implement the following methods to ensure correct
+functioning of [`getu`](@ref) and [`getp`](@ref) for value providers that save the parameter
+timeseries. Note that there can be multiple parameter timeseries, in case different parameters
+may change at different times.
