Please keep the discussion to the mailing list so others can
benefit-from/contribute-to the conversion.

the code I send is for the programmable filter!!!

if you are using a python script these are the lines to use (generated
with python trace in ParaView):
the code in the Script variable of the programmable filter is always
very ugly. you can put the source in a file extra file and use the
execfile() function of python to call it.

#--- begin code ---
# create a new 'Programmable Filter'
programmableFilter1 = ProgrammableFilter(Input=waterPropertiesnc)

# Properties modified on programmableFilter1
programmableFilter1.Script = 'pdo =
self.GetOutput();\npdo.ShallowCopy(self.GetInput());\na =
self.GetInput().GetInformation().Get(pdo.DATA_TIME_STEP());\n# this is
your convertion routine\ntime_label = "Days from 12/12/1800 = " +
str(a*100)  + ":" + str((a*100)%2) + " ...days"\nlabel =
vtk.vtkStringArray();\nlabel.SetNumberOfComponents(1);\nlabel.Resize(1);\nlabel.SetName("TimeLabel");\nlabel.SetValue(0,time_label);\npdo.GetFieldData().AddArray(label)\n'

programmableFilter1.RequestInformationScript = ''
programmableFilter1.RequestUpdateExtentScript = ''
programmableFilter1.PythonPath = ''

annotateGlobalData1 = AnnotateGlobalData(Input=programmableFilter1)

# show data in view
annotateGlobalData1Display = Show(annotateGlobalData1, renderView1)

#--- end code ---

don’t forget to do the time conversion in the script!!!

Paraview. I have a paraview script that read netcdf data which has time
axis given as "days since 1970-01-01
> >     00:00" (Epoch Time). This gives problem if I want to show the
real time of the data in the animation window. What I would like to have
shown are the date as
> >     4-8-2003, 00:00 etc. and it shows big number like 19521, 19522.
