[Paraview] Using real timesteps in pvd files

[Christian Wellmann]

Thanks Stephen and John for your quick answers.
Unfortunately any changes to the group and/or part tag not seem to
solve the problem.
What is strange is that, although ParaView seems to read an int value,
it is able
to handle

<DataSet timestep="-922337203685477580825263735124730" group=""
part="0" file="sp_test0000000.vtp"/>
<DataSet timestep=" 922337203685477580825263735124730" group=""
part="0" file="sp_test0002498.vtp"/>

correctly, what gives me

Index      Value
0            -9.22337e+32
1             9.22337e+32

in the time table although the values are out of range of any standard
integer representation I guess.
However, as a workaround -considering the large range of representable
integer values- I will simpliy
change my scale to micro- or even nano-seconds to get integer time values.
