Hello,

I want to measure the time for each operation (in seconds) in my catalyst in situ script. I tried using the python timers but it complains that it does not recognize it.

[`vtkTimerLog`](https://vtk.org/doc/nightly/html/classvtkTimerLog.html) can be used for that.

```auto
from paraview.vtk.vtkCommonSystem import vtkTimerLog
l = vtkTimerLog()
l.StartTimer()
...
l.StopTimer()
print ("%f in seconds" % l.GetElapsedTime())

```
