[Utkarsh Ayachit]

Michael,

Hard to say. If you could share the code with a sample dataset to
reproduce the problem, that'd make it easier to detect the issue.

However, when reading only a single file results in always showing “0” in the simulation time field, although I added the XML code also to the normal (i.e. non-fileseries) reader plugin.
