Current Method for Resetting Variables

I have various Create Date&Time nodes that pass execution date & time to a variable. These nodes work well using KNIME Desktop whenever the whole workflow is reset and run.

However, my use case requires the workflow to be run through Task Scheduler.

The “-reset” in the trigger syntax doesn’t do the trick, but then I read somewhere here that the variables need to be administered via right click workflow name > Workflow Variables.

Two questions here:

1.

Can the variables I created just be entered here, or do I need to create them from scratch and re-point to the global versions of the workflow?

1.

I also read somewhere this whole functionality is legacy and should not be used. So what does someone need to do in order to get a workflow execution run date reset each time?

I realize this is a use case for KNIME Server, but current constraints are such.
