[vtkusers] Timestep name

If you do as Ken says and use a  numeric time, then ....

There is some very old code in that repo linked above which includes a JulianDayToText class. I used to use this in paraview to take netCDF times and convert them to a string, then add this to my plots with a text source object in paraview which displayed the string.

The code is ancient, and you should not use the netCDF stuff as this was superseded some time back by the one in vtk/paraview. However the text source might give you an idea of how to do what you want, (I just looked in my archive and saw this ftp://ftp.cscs.ch/out/biddisco/netCDF/SO2-1950-2050-5yr-2.avi which was made in 2009 and uses the date/time source to display a simple yyyy/mm/dd dormat time.

In the pvd file, which is just an XML metadata file, you will see tags named DataSet that point to the vtu files. The DataSet tag supports a timestep attribute that takes a number that represents the time value. These time values do not have to be integers and do not have to be regularly spaced.

However, the timestep attribute does have to be a number. You will have to convert your time to some seconds/hours/days from some reference point.

Subject: [EXTERNAL] [vtkusers] Timestep name

I have a timeseries of data that I am saving to a set of vtu files. These load in paraview nicely and play as an animation. However, each timestep corresponds to a date/time (e.g., Oct-01-2010 14:00:00) and I would like this to be displayed. For example, 'Timestep 758' isn't intuitive when dealing with realworld datetimes.
I have tried making a pvd file, but it wasn't not clear how to rename a timestep.

Is there a way of doing this?
