[Paraview-developers] [Paraview] ParaView not reading time in netcdf file

[Dan Lipsa]

David, I was thinking this problem comes from the way ParaView loads time
dependent datasets. However, I created a copy of the file with _51.nc
postfix and ParaView still does not show me the correct time value.
Can you send me two files where the time value is shown correctly?

Thanks,
Dan
