I'll be very glad if you fix this. One big problem, is the TIME_XXX values being
set/reset making updates happen much too frequently. Fixing the information key
modified will be a great relief.<br>

Modified should only be called if something *actually was modified*.<br>

<p class=MsoNormal><font size=3 color=black face="Times New Roman"><span
style='font-size:12.0pt'>I have discovered that just about every time you call vtkInformation::Set,
the vtkInformation object is Modified even when the actual value of the key
stays the same. That should not be the case, should it? All of the
vtkSet* macros avoid calling Modified if the value does not really change. The
problem is that I see in ParaView there are several instances of observes
attached to information objects designed to push updated values from client to
server.<br>
<br>
Does anyone object to me changing the vtkInformation*Key::Set methods to
suppress calling Modified when the value remains the same?<br>
