Hi Utkarsh, Sorry, I forged to keep the paraview mailing list.
Thank you for your answer. I had tried to make a file PVD and I had changed VTK file to VTU. I launched PVD file with xml-base (I think) I can see with TimestepValues are a same that I wrote in PVD file. reader_base.TimestepValues #>>> [0.0, 5.0, 6.0, 10.0] But when I create a movie, the timesteps are bad. I don't understand why? Perhaps I have a bug in my script? I have attached my script and PVD file in my mail. Thanks in advance for your kind help.

TimestepValues is a read-only property. With the legacy reader it's not possible to change the time values for legacy vtk files read as a file series. You can create a pvd file which is an xml file describing the time values for each file, however pvd doesn't support legacy VTK files, you need to write the new xml-based vtk files.
