Original question
I wonder if there is a way how to fix (make constant) specific Time Zero for specific workflow. I mean only time. The day would be same as system date.
Solution
You can define a cardinal timestep for this particular workflow in the workflowdescriptors. For example something like this:
<workflowDescriptor id="xxx" forecast="false" visible="true"> <cardinalTimeStep unit="hour" multiplier="6"/> </workflowDescriptor>
Another option would be to define the times at which the simulation should run explicitly.
<workflowDescriptor id="xxx" name="xxx" autoApprove="true" forecast="true" visible="true"> <cardinalTimeStep times="01:00 07:00 13:00 19:00"/> </workflowDescriptor>
