[Paraview] Using real timesteps in pvd files

[Christian Wellmann]

Hi all. As I now figured out, the problem with my real timestep values
seems to be the decimal separator. Strangely my ParaView 3.4
installation seems to require a comma as decimal separator. So

<DataSet timestep="0,5e-5" group="0" part="0"
file="hour_5121_fall_se0000000.vtp"/>

is interpreted correctly and gives the time value 0.5e-5.
The idea of using a comma as decimal separator came into my mind
using the "Annotate Time" filter, which shows comma separated values
in my installation.
