Regression in 6.1.0: vtkPVDReader fails to parse E+0N scientific-notation timestep values (works in 6.0)

ParaView Support

When opening a .pvd file in ParaView 6.1.0, the PVD reader fails to parse timestep attribute values that are written in scientific notation with an explicit-sign exponent (e.g. 0.8006087E+01). For every timestep entry, it emits:

ERROR: In vtkPVDReader.cxx, line 175
vtkPVDReader (0x...): Could not parse timestep string: 0.8006087E+01 Setting time value to 0

As a result every timestep is set to 0, so the dataset loads with no usable time information.

The same .pvd file:

  • opens correctly in ParaView 6.0.0 with all timesteps parsed, and

  • the referenced .vtu files open without any problem in 6.1.0 (the issue is isolated to PVD timestep parsing, not the underlying data).

I attach the attach the VSLICE_0000.zip to reproduce the issue.
