Hi, I guess you want something like this in your model:

<parameter id="kinetic_constant" value="0"/>
<parameter id="value2" value="10"/>

<listOfEvents>
<event name="my_event">
<trigger>
<math xmlns="http://www.w3.org/1998/Math/MathML">
<apply>
<eq/>
<ci> time </ci>
<cn type="integer"> 12 </cn>
</apply>
</math>
</trigger>
<delay>
<math xmlns="http://www.w3.org/1998/Math/MathML">
<cn type="integer"> 0 </cn>
</math>
</delay>
<listOfEventAssignments>
<eventAssignment variable="kinetic_constant">
<math xmlns="http://www.w3.org/1998/Math/MathML">
<ci> value2 </ci>
</math>
</eventAssignment>
</listOfEventAssignments>
</event>
</listOfEvents>


The kinetic_constant would have the value of 0 until time 12, then it is
set to 10.

Hope this helps...
Greetings,
Hannes
