Filters that generate temporal data should set the vtkStreamingDemandDrivenPipeline::TIME_STEPS() key on their corresponding output's vtkInformation object. Access to any vtkAlgorithm's output information is available via the GetOutputInformation() method.

Using the exodus reader on can.ex2 as an example, here's a vtkpython script to get time step information:

from vtk import *
rdr = vtkExodusIIReader()

This returns a vector of doubles. You can use the integer time step as an index into the vector.
